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 four citizen-entities, all of them are of pension age?

0.2401

Step-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

0,4
