The probability that a randomly chosen person in Botswana 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.

If X IS THE NUMBER of people of age 65 or older in a sample of 6, Construct the probability distribution of X

1 answer

P(65+) = .2

P(<65) = .98

P(2<65 of 6) = .98^2 * .2^4 = ?

Cannot construct probability distribution here.
