It's is a bell shaped histogram

Step-by-step explanation:

This is a binomial distribution problem.

A binomial distribution is a distribution whose experiment has two possible outcomes, a success and failure. The outcomes of the experiment do not depend on each other.

For n trials in a binomial distribution, the probability of getting success:

P(X=x) = n!/[(n-x)!x!] × p^x × q^(n-x)

Where p = success

q = failure

n = 8, p= 40% = 0.4

q = 1-0.4 = 0.6

See attachment for workings and histogram diagram.

From the diagram, the shape of the histogram is bell shaped. It is also known as a normal distribution.
