The probability that in a randomly chosen person is 65 or older is approximately 0.2.
a) What is the probability that in a randomly selected sample of 6 people exactly 4 of them are 65 or older?
b) If X is the number of people of age 65 or older in a sample of 6, construct the probability distribution of X.
c) Compute P(X<2)
d)Compute P(X > 2)
