There is a 47% chance the ball will land on red, 47% chance it will land on black and a 6% chance it lands on green. You decide to roll the ball three times. Using this information answer the following: What is the probability that zero balls land on red? What is the probability that the first two balls land on black and the third lands on green?

A)

P(no red) = (1-P(red))^3 = (1-0.47)^3 = 0.148877 [answer]

B)

P(black, black, green) = 0.47*0.47*0.06 = 0.013254 [ANSWER]
