Homework Q5
Hi, I'm working on the 6th question but I can't get the solution.
I solved Q5 and I found a probability to get on just one sample (N=10) of 0.0047. Then to compute the probability to get at least one sample with , I modeled the number of samples with 0 red marbles with a binomial random variable . Hence, the probability I need is and Finally , so my closest answer is [3] = 0.550, however the solution report [c] as right answer. Where did I make a mistake ? Thank you in advance for your time (and sorry for my english).

Re: Homework Q5
Thank you very much Prof. Yaser !
I did a mistake in calculating the probability of the Homework 4. This was caused by the fact that I used the Hoeffding inequality to compute this probability instead of a simple binomial distribution. Now, I'm wondering a more general question: is this slack between the exact probability one gets with the binomial (in this case) and the bound provided by the Hoeffding inequality typical ? Thank you very much in advance for your answer.

Re: Homework Q5
Yes. Since the bound is the same for cases that have different probabilities, it is forced to be loose in some of the cases.
