Answer #1

The probability that the entire class fails at least one quiz, the same quiz that is, in a month is (0.01)q, where q is the number of days in that month.

Class starts in August.

Givan that failed quizzes are independent from month to month.

probability (the first quiz failed by the entire class is in November)=(1-0.01*31)*(1-0.01*30)*(1-0.01*31)*(0.01*30)

=0.099981
