Question

A spinner has 4 blue sections, 6 red sections and 2 green sections. It is spun 24 times. For numbers 2a. – 2c., circle YES or NO to indicate whether you would expect the spinner to land on the given color the number of times stated.

Answer 1

Blue = YES

Red = NO

Green = YES

Explanation:

Given the distribution of colors on a spinner :

Blue = 4 ; Red = 6 ; Green = 2

Number of spins = 24

Total = (4 + 6 + 2) = 12

Recall:

Probability, P = required outcome / Total possible outcomes

P(red) = 6 /12 = 1/2

P(blue) = 4 / 12 = 1/3

P(green) = 2 / 12 = 1/6

On 24 spins :

Possible number of red = 1/2 * 24 = 12

Possible number of green = 1/6 * 24 = 4

Possible number of blue = 1/3 * 24 = 8
