28 gift bags, 3 chocolate candies, and 2 peppermint candies
There are 20 candies of each of the five colors. The probability that when you select 2 candies at random exactly one of the candies will be orange is: P(exactly one turns out orange out of 2) = 2∙(20/100)∙(80/99) = 0.323232... P ≈ 32%
4 choices for the first letter 3 choices for the second, once the first has been chosen 2 choices for the third, once the first and the second have been chosen 1 for the last So it's 4x3x2x1 = 24
