Question

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is orange.

spinner divided evenly into eight sections with three colored blue, one colored orange, two colored purple, and two colored yellow

Determine P(not blue) if the spinner is spun once.

12.5%
25%
37.5%
62.5%

Answer 1

The total number of possible outcomes is 8, since there are 8 sections on the spinner.

The number of outcomes in which the spinner is not blue is 8 - 3 = 5, since there are 3 blue sections on the spinner.

Therefore, P(not blue) = number of outcomes in which the spinner is not blue / total number of possible outcomes = 5/8 = 0.625 = 62.5%.

So the answer is 62.5%.
