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
