Question

Daniel’s spinner is divided into 8 equal sections.

A spinner divided into 8 equal sections labeled gray, green, red, purple, gray, green, yellow, blue.

He plans to spin it 80 times. Which equation predicts the number of times that he could spin green?
P (green) = StartFraction 1 over 8 EndFraction (80)
P (green) = StartFraction 2 over 8 EndFraction (80)
P (green) = StartFraction 3 over 8 EndFraction (80)
P (green) = one-half (80)

Answer 1

There are 2 green sections out of 8, so P(green) = 2/8. For 80 spins: P(green) = (2/8)(80) = 20. Thus the correct equation is P(green) = (2/8)(80).
