Hi

A quiz consists of 5 true/false questions followed by 

2 multiple choice questions with four possible answers.

Assuming only one of the four possible answers is correct for @ mulitple choice:

P(answering all incorrect) = (.5)^5*(.75)^2 = .0176

P(at least one correct) = 1 - P(none correct) = 1-.0176 = .9824
