Question

In a game, the probability of winning is 1 out of 5. How many times could Lisa expect to win if she plays the game 85 times?

Answer 1

17 wins

Explanation:

Given

P(winning) = 1/5

Number of games = 85

The number of winnings could simply be calculated as the product of the probability and number of games played.

Expected number of winning : P(winning) * number of games

Expected number of winning = 1/5 * 85 = 17 wins
