Diana Chavez · Answer 1

To find the change that Ben has of winning out of 200 chances, you will find out what percent chance he has using the percents of the other 2 players.

100% - 50% (Cam) - 20% (Justin) = 30% for Ben

30% of the 200 attempts would be calculated as:

0.30 x 200 = 60.

You should expect Ben to win 60 times, choice C.

Rex Butler · Answer 2

The best prediction for Ben would be 60 wins out of 200.

If Justin wins 20% of the time and Cam wins 50% of the time, that leaves 30% of the wins for Ben.

To find his predicted amount out of 200, just multiply it by 30%.

0.3 x 200 = 60 wins
