There are 10 purple, 5 yellow, 2 green, and 3 red jelly beans in a bowl. Write a sentence that explains how likely it is for a purple, red, or yellow to be chosen in one pick.

Either-or probabilities are added.

10/20 + 3/20 + 5/20 = ?

To determine how likely it is for a purple, red, or yellow jelly bean to be chosen in one pick, we need to calculate the probability of picking a purple, red, or yellow jelly bean out of the total number of jelly beans in the bowl.

First, let's find the total number of jelly beans in the bowl by adding up the quantities of each color: 10 purple + 5 yellow + 2 green + 3 red = 20 jelly beans in total.

Next, let's calculate the probability of picking a purple, red, or yellow jelly bean. We divide the number of purple, red, and yellow jelly beans by the total number of jelly beans: (10 purple + 5 yellow + 3 red) / 20 total jelly beans = 18 / 20 = 0.9 or 90%.

Therefore, the probability of picking a purple, red, or yellow jelly bean in one pick is 90%, meaning it is highly likely that one of these colors will be chosen.
