Question

Sarah has drawn 4 circles. She wants to paint each of them red, blue, or green and wants to use at least 2 colors. How many ways can she do this?

A) 6
B) 9
C) 12
D) 18

Answer 1

The number of ways she can draw the circle with at least 2 colors is 12

How many ways can she draw the circle with at least 2 colors

From the question, we have the following parameters that can be used in our computation:

Colors = 3

Circles = 4

Using the above as a guide, we have the following:

Ways = Colors * Circles

Substitute the known values into the equation

Ways = 3 * 4

Evaluate

Ways = 12

Hence, the number of ways is 12
