Consider an experiment involving the game spinner pictured below. A 20 trial experiment is conducted to determine the probability of landing on blue. Assume the spinner is perfectly balanced and the probability of each color is the same. What is the probability of landing on blue 5 times?

1/4

Step-by-step explanation:

To determine the probability of landing on blue, you divide by the total number of spins.

In this experiment, the probability of the spinner landing on blue after 20 spins would be 15%.

This makes the probability of landing on blue to be:

Pr (landing on blue) / Pr (total trials) = 5/20

This gives 1/4

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
