Probability question. will choose BEST answer…need help :( ?

If you could give me an explanation of how to do this I would GREATLY appreciate it. Will choose best answer

As part of its quality-control program, the video cartridges produced by Starr Communications are
subjected to a final inspection before shipment. A sample of 7 cartridges is selected at random from each lot of cartridges produced, and the lot is rejected if the sample contains one or more defective cartridges. If 1.7% of the cartridges produced by Starr is defective, find the probability that a shipment will be accepted.

admin answers:

W need to find out the size of the lot to compute the defectives. Then we subtract defectives from the the lot size and divide by the lot size , multiply by 100 to obtain the %of a good cartridges per lot.
Y= lot size

7 samples per lot are taken so what is the size of the lot?

Y / 7 -1 = 1
y = 14

the % defective is 1.7% , 14(1.7)/100 = 0.238 defects per lot

14 – 0.238 = 13.76 good cartridges, —-> 13.76/14*100 = 98.3% good cartridges per lot which is the
probability of success in any one trial. So the probabilities the shipment will be accepted are unknown.But there is more on the calc.of the probability of acceptance of the shipment.For we have to make use of a formula called the Binomial Probability Formula which give the probability of sucess given the values already calculated.

P(x) = nCx *p^x *q^(n-x) where the definitions are:

n = number of trials = 7
x= number of succees among trials = 6
p = probability of success in any one trial = 98.3%
q= probability of failure in any one trial ( 1-p )
nCx = combinations of n items , choose x

from here is a matter of substitution: nCx = 7C6 = 7! / 6 !(7-6)! = 7*6! / 6! (1)! = 7!

So we have, P(6) = 7 *(0.983)^6 * (0.017)^(7-6) = 6*(0.9022)(0.017) = 0.107 = 10.7% which is the
the probability of the shipment being rejected, then 100- 10.7
= 89.3 % being accepted.

Betty asks…

If you are a witness/victim in a court case can you refuse to answer a question?

So, I have court tomorrow morning, and I’m stressing obviously. But I had a question about if your aloud to do this. So I am the victim in this case which I won’t get into details and it’s a juvenile case just so you know if that changes anything , but when I go to testify, if the offenders public defender asks me a question that has NOTHING to do with the case at all, that can’t help the case, has literally no connection to it can I CHOOSE to not answer the question? Can I like object? Or is that illegal and will I get in trouble? Because I honestly have no idea and when I talked to the District Attorney for the case he said that the public defender may ask some questions that are random that don’t have a lot to do with the case like for example: she may ask about me cosplaying (dressing up as a character from an anime) because the fact that I do could make me look bad or something.
So for a question like that would I be aloud to withhold an answer?
They didn’t tell me and at the time I didn’t ask so if anyone knows about anything like that, please answer or if you even have a thought on it or just your opinion on if you THINK it would be acceptable not to answer, please tell me. Thank you!
ADD: okay, since I can’t refuse to answer my main main concern is if they ask a question like per say “did your ex-boyfriend hit you,” or something to that effect (this person not being the person in trouble) could they get in trouble if I answered “yes.” ? Even if I didn’t want them to get in trouble?

admin answers:

If you think the question is unfair – say so and explain why you feel its unfair.

You ask ‘Can I like object?’ – no that will be for the D.A.to do, where he must give reason such as – relevence to the case –

The question of ‘did your ex-boyfriend hit you’ the question would be ‘How many times did your former boyfriend hit you – and where di they hit you?’ The significance of the question esablishes the assault, – the physical contact as well as the number of times it happens. This forms a pattern of actions as well as a history.

I think you are getting worked up with out reason, but you can always talk to a court official about your concerns.

Repost, random questions, answer the ones you can, 10pts!?

Thanks to everyone who posted before, I just had to revise some wording in the questions to clarify.

1) I rode English for the… third? time yesterday in a hunt saddle! I loved it! I ride quite well western, and I have been riding western for 4-5 years, so I understand walk trot canter cues, sitting deep, heels down, etc. I could use advice on these two issues:
a. The stirrups slip back from the ball of my foot to the heel of my boot! This NEVER happens to me western, although sometimes I put my heels down a bit too much. Has anyone heard of putting your heals too far down in English stirrups so that not enough weight is on the ball of your foot, and the stirrup slips back? Could this be the problem? Any tips?
b. I am MUCH better at posting and keeping my stirrup when traveling counter-clockwise than clockwise. Is it normal to be better in one direction?
Any other advise is much appreciated! *NOTE* I DO NOT want a western vs. english debate here. I respect both types of riding, and honestly don’t care if you think that english is abusive, or that western doesn’t take skill.

2) My 4H horse quiz bowl team won Regional, State, and now we are headed to Nationals!! Nationals are in Lexington, Kentucky, and the Breeders Cup will be going on during the event, so we get to hang out there!! But anyways, has anyone been to the Breeders Cup? What’s your experience? Any major events that you recommend!?

3) *OK, please READ. I don’t want to be yelled at or lectured.* So, I might lease a horse over the summer that my instructor recommended. He is a English and Western pleasure horse, which is EXACTLY what I’ve been looking for! He is well trained in both, and I’m a fairly good rider, but I’m wondering if he could be too advanced for me. What I mean is that could I be able to handle him fine, and actually look rather nice on him, but harm his training by not challenging him to his full capacity? Can I handle him well, and look nice on him, but damage his training by not always demanding the best from him, because I am not at that level to compete?

Thanks, I WILL chose a best answer. If you don’t know all of them, just answer the ones you can!

admin answers:

1- Definately shorten your stirrups.The correct position for english riding is to push your weight down into your heels.That will help to keep your legs in the right position. Everyone,very much like horses has a stronger and a weaker side,so its very common to ride better on one particular rein,meaning clock wise or anti clockwise.Unfortunately you`ll always find that your weak side is also the horses weak side usually due to the rider not riding the horse evenly balanced,and lets be honnest we are all i think gulity of that. 2-No,never been. 3-Do you trust your instructor? Surely they wouldn`t have recommended this horse if they didnt think you were capable of riding him.I really do understand your predicament,and I understand the worry of you ruining him but I would be more worried that someone who didnt have a clue what they were doing but thought they were an expert would ruin him.You are obviously very compassionate and its lovely to hear someone being totally honnest regarding their ability but I think that you could maybe learn alot from this advanced horse.We are all on a learning curve.Trust me,I`ve been riding 21 years and Im still learning.I`d say go for it! You wont know til you try him and if need be you`ve always got your instructor to help should you run into any teething problems
