(Use computer) Assume that X is a hypergeometric random variable with N = 42, S = 15, and n = 9. Calculate the following probabilities. (Round your answers to 4 decimal places.)

Solution

X~hypergeometric(N=42,S=15,n=9)

so using computer that is minitab software we get

a) P[X=7]=0.0051

b)P[X>=2]=1-P[X<=1]=1-0.0852=0.9148

c)P[X<=4]=0.8435
