Eight college students have applied for interships at a local firm. Three of them will be selected for interviews.

Four of the eight students are from BB State College. What\'s the probability that all three of the interviewed students are from BB State College?

Solution

x: number of BB state college interviewed

This is a binomial distribution.

n=8

p=3/8=0.375

p(x)=nCxp^x(1-p)^n-x

p(x=3)=0.281632. this is calculted by subsituting n=8,x=3,p=0.375 in the above pmf.
