First find the radius of the circle:

The formula for circumference = C = 2 x PI x radius

The circumference would be the length of the fence.

100 = 2 x 3.14 x radius

100=6.28 x radius

Radius = 100/6.28

Radius = 15.92

Area of a circle = PI x radius^2

Area = 3.14 x 15.92^2

Area = 795.82 square feet.

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=5, p=0.4)$
