Maria is coloring in triangles, squares and circles using 3 colors red blue and yellow or Maria only uses a color on each shape one time how many different combinations can she make?

The number of possible color combinations that she can make = 6

Step-by-step explanation:

The number of available colors = 3

The question states that Maria only uses a color on each shape at a time,

The number of possible color combinations that she can make = 3!

n! = n * (n - 1) * (n-2) * ... * 1

3! = 3 * 2 * 1

3! = 6 combinations

The number of possible color combinations that she can make = 6
