Suppose that 60% of the voters in a state intend to vote for a certain candidate. what is the probability that a survey polling 5 people reveals that at most 2 voters support the candidate.

0.31744

Step-by-step explanation:

Binomial probability distribution 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 succes in each trial.

Given : The probability that the voters in a state intend to vote for a certain candidate:  

Now, the probability that a survey polling 5 people reveals that at most 2 voters support the candidate will be :-

Hence, the probability that a survey polling 5 people reveals that at most 2 voters support the candidate = 0.31744

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
