Question

A spinner is divided into five colored sections that are not of equal size: red, blue,

green, yellow, and purple. The spinner is spun several times, and the results are
recorded below:
Spinner Results
Color Frequency
Red
7.
Blue
13
Green 20
Yellow
14
Purple 9
Based on these results, express the probability that the next spin will land on blue or
green or purple as a decimal to the nearest hundredth.

Answer 1

0.67

Explanation:

The total number of spins is

7 + 13 + 20 + 14 + 9 = 63

The numbers of spins that landed on blue, green, and purple are:

13, 20, 9

Total blue, green, purple: 13 + 20 + 9 = 42

Based on the spins that are tabulated, the probability the spinner will land on blue, green, or purple is

42/63 = 2/3 = 0.67
