Question

4) The probability that Abel wins a

game is. If Abel plays the game 80
5
times, how many times can he expect
to win the game?

Answer 1

If the probability that Abel wins a game is 5/8, then the probability that he loses the game is 1 - 5/8 = 3/8. If Abel plays the game 80 times, then he can expect to win the game 5/8 * 80 = 40 times, because the expected value of a probability is the probability times the number of trials. Therefore, Abel can expect to win the game 40 times if he plays it 80 times.
