The probability you win a game is 0.40. If you play the game 90 times, what is the most likely number of wins you will get? This is the same is the mean of the binomial distribution with N=90 and p=0.40, and it is also the expected value of playing the game 90 times.

A lottery offers one $900 dollar prize, one $700 prize, three $300 prizes, and five $100 prizes. One thousand tickets are sold at $5 each. Find the expectation if a person buys two tickets. Assume that the player's ticket is replaced after each draw and that the same ticket can win more than one prize. Round to two decimal place for currency problems. The expectation if a person buys two tickets is $_______?
