Question

A box of colored pencils contains exactly 6 red pencils. The probability of choosing a red pencil from the box is 2/7. How many of the pencils in the box are not red?
a) 5 b) 15 c) 21 d) 30

Answer 1

To begin with, you need to find the total number of pencils, which is 21.
Then you subtract 21 from 6 (red pencils) to find how many are not red.

The answer is B. 15 pencils are not red.
