Question

A spinner has three unequal sections: red, yellow, and blue. The table shows the results of Nolan's spins. Find the experimental probability of landing on each color. Enter your answers as simplified fractions.

Red 12
Yellow 18
Blue 5

Answer 1

red: 12/35

yellow: 18/35

blue: 1/7

Explanation:

The experimental probability is the total number of each outcome over the total outcomes. The total outcomes would be the sum, 12 + 18 + 5, or 35.

If we are looking for the experimental probability of red, we divide the spins on red by the total:

red -
`(12)/(35)`

If we are looking for the experimental probability of yellow, we divide the spins on yellow by the total:

yellow -
`(18)/(35)`

If we are looking for the experimental probability of blue, we divide the spins on blue by the total:

blue -
`(5)/(35)` =
`(1)/(7)`
