Question

Justin, Cam, and Ben are playing a board game where exactly one player will win. Ben estimates that Justin has a 20%, percent chance of winning each game and that Cam has a 50% percent chance of winning each game.

What is the probability that Ben will win the board game?

Answer 1

30%

Explanation:

If Justin has a 20% chance and Cam has a 50% chance that adds up to 70%

But you need to get to 100% so all you do is

70 - 100 = 30

30%
