Need help with a lottery problem with 2 questions:
The probability of winning a free ticket (for matching 2 of 5 numbers) in a particular state lottery is 1 in 10; the probability of winning cash for matching 3 of 5 numbers is 1 in 103; and the probability of winning cash for matching 4 of 5 numbers is 1 in 3387. The probability of winning cash for choosing 5 of 5 winning numbers is 1 in 575,757. (The amount of cash won depends on how many winners split the prize.)
