10/12 + 1/2
Get a common denominator.
1/2 = 6/12
6/12 + 10/12 = 16/12
16/12 = 1 4/12 = 1 1/3

Answer: 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
Step-by-step explanation:
We need to say that is equivalent to what.
We know that, (3)² = 9
So,
We can write
And
So,
So, is equivalent to .
Hence, this is the required solution.
