Dr. Christou, can you please give me a hint on how to approach numbers 2 and 7 on this assignment? I am kind of lost. Thank you.

For problem 2,the necessary formula was described in class. There is no way to solve for the variable n when equating this formula to 1/2, so you have to resort to plugging in values of n until you get the right answer. For question 7, all you need is the expected value formula. The table at the end of the assignment provides you with the values you need to fill in the formula. The rest is computation.

Thank you. For the probability p(x) do I just use the percentages/100 correct? and for number 2 I forgotten which formula it was..is it 365!/(365-n)!(365^n) ?

Correct. in both cases.
