The answer for this question is B
Answer:
Mean = 0.48
Step-by-step explanation:
Given that according to the Masterfoods, we have M&M manufactures different colours of peanuts.
Colour Brown Yellow Red Blue Orange Green Total
Percent 12 15 12 23 23 15 100
We can sort this as brown 12% and non brown 88%
X no of brown in the selection of 4 peanuts is binomial since there are two outcomes and each is independent.
P(X=r) = 4Cr (0.12)^r (0.88)^(n-r)

E(x) = np = 
You need to find the radius. It is half the diameter
The radius is 2.5
C=2 pi r
C=2 times 2.5= 5. 5 times pi= 15.7
The answer is 15.7
