The spinner has 8 divisions, where 2 of those division have the number 1, and the other 6 divisions numbers greater than 1. The probability of getting a number greater than one on a single spin is given by the ratio between the amount of divisions with numbers greater than 1 by the total amount of divisions, which is


(6)/(8)=(3)/(4)=0.75

The probability of getting a number greater than one in a single spin is 0.75.

Each spin is an independent event. The probability that on both spins the arrow will stop in a number greater than one is given by the product between the probabilities of getting a number greater than one on each spin, and both of them are 0.75. Their product is


(3)/(4)*(3)/(4)=(9)/(16)=0.5625

If the spinner is spun twice, the probability that an arrow will stop on a number greater than 1 on both spins is 0.5625.
