Answer: 0.2965
Step-by-step explanation:
Given : The proportion of voters in a city favor of a $0.01 tax increase. =0.30
The number of voters are selected at random =8
Binomial probability formula :-
, where P(x) is the probability of getting success in x trials, n is total number of trials and p is the probability of getting success in each trial.
Now, the probability that exactly 2 of them will vote in favor of the tax is given by :-

Hence, the probability that exactly 2 of them will vote in favor of the tax = 0.2965
