Question 973234: There are 20 students who take the final exam in Statistics. The probability that a student will pass is 0.78.
Event A: None of the students fail.
Define A complement and find P(A complement)
I did the math as follows:
P(At least one student fails) = 1- P(all pass)
=1-(0.78)^20
=0.993
Is this correct? Thanks!
