Question

Cup A has 50% pink balls and 50% green balls. Cup B has 50% orange balls and 50% green balls. You and you friend both draw one chip from each bowl. What is the probability that you both draw at least one white chip?

Answer 1

By white i mean green.

Answer 2

50%

Answer 3

the key word is "at least one green chip"

there are 3 possibilities

1. green, non-green = .5(.5) = .25
2. non-green,green = .25
3 green, green = .25

so the prob of at least one green = .75 or 75%
