These are two independent events so the probability of both events is just the product of the probability of each event. We have:

Pr ( first spin is on red ) = 8 / 10 = 4 / 5 and

Pr ( second spin is on the rest of the sections ) = 2 / 10 1 / 5 Thus we have

Pr ( first spin is on red and second spin is on the rest of the spinner = ( 4 / 5 ) x ( 1 / 5 ) = 4 / 25
