Spin this spinner once (goes to ten.) Predict in 40 spins how many times you would spin a number less than 8.

Answer: 35 spins

Step-by-step explanation:

First, we will find the probability of a number less than 8.

      [tex]\displaystyle \frac{\text{Number less than 8}}{\text{Total number of numbers}} =\frac{1,2,3,4,5,6,7}{1,2,3,4,5,6,7,8} =\frac{7}{8} =0.875[/tex]

Next, we will predict how many of the 40 spins will be a number less than 8. In mathematics, "of" means multiplication. We will multiply 0.875 by 40.

      [tex]\displaystyle 0.875\text{ chance}*40\text{ spins}=35\text{ spins}[/tex]
