Question

A package of cups contain exactly 6 blue cups.The probability of choosing a blue cup from the package is 3/5.How many of the cups in the package are not blue?

Answer 1

There are 4.

Explanation:

If there are 6 blue cups, and the blue cups make up 3/5th of the total cups, you can divide 6 by 3/5 to find the total amount of cups, which is 10. Then, you do 10-6 to find how many cups in the package are not blue.
