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
Blue
Green
Yellow
Purple
12
3
20
20
15
Based on these results, express the probability that the next spin will land on red or
blue or yellow as a percent to the nearest whole number.

Answer 1

70%
i too. the tezttttt

Answer 2

The total number of spins recorded is:

12 + 3 + 20 + 20 + 15 = 70

The probability of landing on red or blue or yellow is the sum of their frequencies divided by the total number of spins:

(12 + 3 + 20) / 70 = 0.5

Multiply by 100 to express as a percentage:

0.5 x 100 = 50%

Therefore, the probability that the next spin will land on red or blue or yellow is 50% to the nearest whole number.
