Solutions

Expert Solution

The probability that randomly selected peanut is yellow will be 0.15 so the probability that randomly selected Peanut is not Yellow will be

P(not Yellow) = 1 - P(Yellow) = 1 - 0.15 = 0.85

Answer: 0.850

---------------------------

The probability that a randomly selected peanut M&M is green or yellow is

P(green or yellow) = P(green) + P(yellow) = 0.15 + 0.15 = 0.30

Answer: 0.300

--------------------------------------

The probability that two randomly selected peanut M&M’s are both red is

P(both red) = P(red) * P(red) = 0.12* 0.12 = 0.0144

Answer: 0.014

-----------------------------------------------

From given information:

P(not Green) = 1 - P(Green) = 1 - 0.15 = 0.85

The probability that none of five are green is

Answer: 0.444

------------------------------------------------

From the complement rule, the probability that at least one of them is green is

Answer: 0.556
