Question

A spinner with 9 equally sized slices is shown below 7 slices are yellow 1 is blue and 1 is red the dial is spun and stops on a slice at random what are the odds in favor of landing on a yellow slice

Answer 1

The probability of each slice is 1/9 because it is divided into 9 slice

we have 7 slices in yellow therefore the probabiliy is

`P(yellow)=(1)/(9)+(1)/(9)+(1)/(9)+(1)/(9)+(1)/(9)+(1)/(9)+(1)/(9)=(7)/(9)`

the odds in favor of landing on a yellow slice is 7/9=0.778
