The probability that a randomly chosen citizen-entity of Cygnus is of pension age is approximately 0.7. What is the probability that, in a randomly selected sample of 3 citizen- entities, all of them are of pension age? Round your answer to four decimal places. Solution P(1st is of pension age)=0.7 P(2nd is of pension age)=0.7 P(3rd is of pension age)=0.7 P(1st is of pension age AND 2nd is of pension age AND 3rd is of pension age)= 0.7x0.7x0.7x=0.3430.
