Question

Steve has a spinner with 5 equal sections that are colored red, orange, blue, green, and yellow. If he spins the spinner 15 times, how many times can he expect to spin a color that is not green?

Answer 1

Steve has a spinner with 5 equal sections, and he spins it 15 times. The probability of spinning a color that is not green is 4/5, since there are 4 colors that are not green out of a total of 5 colors. To find the expected number of times he can spin a color that is not green, we can multiply the probability of spinning a non-green color by the total number of spins:

Expected number of non-green spins = probability of non-green spin x total number of spins

Expected number of non-green spins = (4/5) x 15

Expected number of non-green spins = 12

Therefore, Steve can expect to spin a color that is not green 12 times out of 15 spins.
