With a certain scratch-off lottery ticket a player can either win $100 or win nothing. The probability that a person win $100 on a single ticket is 0.258. If Andy buys 10 tickets, what is the probablity of winning $100 each on 2 of the 10 tickets? Round your final answer to 5 decimal places.
Solution
This is Binomial with n = 10 and p = 0.258
P(2) = 10C2 (0.258^2)(1 - 0.258)^8 = 0.27522
