Let the age of the son be x, then the age of the father = 6x
x + 6x = 42
7x = 42
x = 42/7 = 6
Therefore the age of the son is 6 while the age of the father is 6(6) = 36.

Answer: 0.1840
Step-by-step explanation:
The binomial probability formula :-
, here n is the number total of trials , p is the probability of getting success in each trial and P(x) is the probability of getting success in x trial.
Given : The probability of the community favored building a police substation in their neighborhood = 0.64
If 14 citizens are chosen, then the probability that exactly 8 of them favor the building of the police substation will be :-

Hence, the probability that exactly 8 of them favor the building of the police substation = 0.1840
