Question

An experiment consists of spinning a spinner. Use the results in the table to find the experimental probability of the spinner not landing on red.

Red = 8
Blue = 7
Green = 9
Yellow = 6

A. 3/5
B. 11/15
C. 2/5
D. 4/15

Answer 1

Probability(Not red) = 11 / 15

Explanation:

Given:

Outcomes;

Red = 8

Blue = 7

Green = 9

Yellow = 6

Find:

Probability(Not red)

Computation:

Probability(Not red) = 1 - Probability(red)

Probability(Not red) = 1 - [Number of red/ Total]

Probability(Not red) = 1 - [8/(8+7+9+6)]

Probability(Not red) = 1 - [8/30]

Probability(Not red) = 1 - [4/15]

By taking LCM

Probability(Not red) = (15 - 4) / 15

Probability(Not red) = 11 / 15
