M&M plain candies come in various colors. According to the M&M/Mars Department of Consumer Affairs, the distribution of colors for plain M&M candies is as follows.
Color Purple Yellow Red Orange Green Blue Brown
Percentage 21% 17% 19% 9% 8% 6%. 20%
Solution:
a) Find P(purple or green candy ) :
From the table,
P(purple candy) = 20% = 0.21
P(green candy) = 8% = 0.08
P(purple or green candy) = P(purple candy) + P(green candy)
= 0.21 + 0.08
= 0.29
(b) Find P(not red ).:
P(red candy) = 19% = 0.19
P(not red candy) = 1 - P(red candy)
= 1 - 0.19
= 0.81
(c) Find P(brown candy):
P(brown candy) = 20% = 0.20
Therefore,
P(purple or green candy) = 0.29
P(not red candy) = 0.81
P(brown candy) = 0.2
