In: Statistics and Probability
According to Masterfoods, the company that manufactures
M&Ms, 12% of peanut M&Ms are brown, 15% are yellow, 12% are
red, 23% are blue, 23% are orange and 15% are green. Assume that
selecting multiple M&Ms are independent events. (Round your
answers to three decimal places, for example: 0.123)
Compute the probability that a randomly selected peanut M&M is
not yellow.
A:
Compute the probability that four randomly selected peanut M&Ms
are all yellow.
A:
If you randomly select five peanut M&Ms, compute that
probability that none of them are red.
A:
Answer:
Given that,
According to Masterfoods,
The company that manufactures M&Ms, 12% of peanut M&Ms are brown, 15% are yellow, 12% are red, 23% are blue, 23% are orange and 15% are green.
Assume that selecting multiple M&Ms are independent events.
(a).
The probability that a randomly selected peanut M&M is not yellow:
Given 15% are yellow,
The probability that a randomly selected peanut M&M is not yellow=P[Peanut is not yellow]
=1-0.15
=0.85
Therefore, the probability that a randomly selected peanut M&M is not yellow is 0.85
(b).
The probability that four randomly selected peanut M&Ms are all yellow:
Given 15% are yellow,
The probability that four randomly selected peanut M&Ms are all yellow=P[ 4 randomly selected peanuts are yellow]
=0.150.150.150.15
=0.00051
=0.001( Approximately)
Therefore, the probability that four randomly selected peanut M&Ms are all yellow is 0.001.
(c).
The probability that none of them are red:
Given 12% are red.
If you randomly select five peanut M&Ms, that none of them red=P[ 5 randomly selected peanuts are not red]
=(1-0.12)(1-0.12)(1-0.12)(1-0.12)(1-0.12)
=(1-0.12)5
=(0.88)5
=0.5277
=0.528(Approximately)
Therefore, the probability is 0.528
