ok i will try it out later, have to work on the mid term exams today.
I would also like to know which software or calculator are you using for these questions
Thank you~
I am re calculating it right now.
By the way, just want to know if you have learnt survival model before?
thank you i have to hand it in 1 hour later, i should ask you earlier. i got 3.5500 for k=10
ic, i cant find the expected value for n=100 with my scientific calculator, can u gimme a hand? ty very much
the general formula of the expected value in part b, u show a lot of summations in the formula, k is the total number of players, j is a dummy , how about n?
k stands for the total no. of players , how about n?
I have placed it between the

how do you think?
please tell me if it is not correct
I manage to finish this question ty
would you like to show me the steps for part b?
for part a, one of my friend told me dat
he used (a-b)^n as example, he expanded it and found summation from 0 to n, (-1)^i * nCi * a^(n-i) * b^i
when a = b = 1, it will look like the same as part a and will equal to 0 no matter n=0 or not
how do you think?
yeah i also get this ans in part a
but i dunno how to do part b after expanding nCi and iCm.
