I'm having a tough time with this problem and was hoping someone coule help.
It involves the Mega Millions lotter.
5 numbers are selected from the intergers 1-56 (without replacement) and the special 6th ball is selected from a new set of number 1-46. A winning ticket must have correctly picked the 5 numbers from the first set and the 1 number from the 6th set.
I know the probability of winning with 1 ticket is
The question is, if exactly $200,000,000 is wagered (at $1 per ticket) what is the probability of 2 or fewer winners? And what is the expected number of winners?
Any help would be greatly appreciated.
You are expected to use the Poisson approximation to the Binomial distribution for this problem.
