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 6
Green 12
Yellow 19
Purple 19
Based on these results, express the probability that the next spin will land on blue as a fraction in simplest form.

Answer 1

Answer: 2/21

Step-by-step explanation

Add up the frequencies:

7+6+12+19+19 = 63

Out of those 63 total spins, 6 of them landed on blue.

The empirical (aka experimental) probability of landing on blue is therefore 6/63 = 2/21
