Step-by-step explanation:
If you use the formula P(r)=nCrP^rq^n-r.
P is the probability of success = .25
n is the total number of questions = 8
r is the total number of questions that Johnni got correct = 3
q is the probability of getting an answer wrong = .75
Plug all of these values into the formula, and you should get roughly .208.
