According to a recent study, 12% of peanut M&M's are brown, 3% are yellow, 21% are red, 28% are blue, 28%
are orange, and 9% are green. Assume these proportions are correct and suppose you randomly select six
peanut M&M's from an extra-large bag of the candies. Calculate the following probablities. Also calculate
the mean and standard deviation of the distribution. Round all solutions to four decimal places, if
necessary.
Compute the probability that exactly three of the six M&M's are blue.
P(r = 3) =
Compute the probability that three or four of the six M&M's are blue.
P(x = 3 or x = 4)
Compute the probability that at most three of the six M&M's are blue.
P(a ≤ 3) =
Compute the probability that at least three of the six M&M's are blue.
P(x > 3)
If you repeatedly select random samples of six peanut M&M's, on average how many do you expect to be
blue?
"
blue M&M's
With what standard deviation?
σ
blue M&M's
