Percentage 19% 17% 22% 10% 6% 8% 18%

(a)

P(green candy and blue candy) = 0

Yes. Choosing a green and blue M&M is not possible

So, the outcomes are mutually exclusive. As these outcomes are mutually exclusive,

P(green candy or blue candy) = P(green candy) + P(blue candy) = 0.06 + 0.08 = 0.14

(b)

P(yellow candy or red candy)) = 0

Yes. Choosing a yellow and red M&M is not possible.

So, the outcomes are mutually exclusive. As these outcomes are mutually exclusive,

P(yellow candy or red candy)) = P(yellow candy) + P(red candy) = 0.17 + 0.22 = 0.39

(c)

P(not purple candy) = 1 - P(purple candy) = 1 - 0.19 = 0.81
