In a particular county 30% of the population has a college degree. A jury consisting of 12 people is selected at random from the county. What is the probability that exactly four of the jurors have a college degree? .23451 .49567 .00047 .30000 .23114

Solution

p = 0.3

n = 12

This is a binomial distribution

P(X = 4) = 12C4 * 0.3⁴ * (1 - 0.3)^12-4

              = 0.23114

So, the correct option is Option-E) 0.23114
