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.
