Answer:0.2401Step-by-step explanation:The binomial distribution formula is given by :-where P(x) is the probability of x successes out of n trials, p is the probability of success on a particular trial.

Given :The probability that a randomly chosen citizen-entity of Cygnus is of pension age† is approximately: p =0.7.Number of trials : n= 4

Now, the required probability will be :Thus, the probability that, in a randomly selected sample of four citizen-entities, all of them are of pension age=0.2401
