However, if he hits the snooze bar, 70% of the time he makes to class on time.

Find the probability that Kobe hits the snooze bar AND makes to class on
time (P(Hit snooze bar AND On time) = ?). Show your work!*
The probability that events A and B both occur can be found using the
general multiplication rule
P(A and B) = P(ANB) = P(A) · P(BA)
where P(BA) is the conditional probability that event B occurs given that
event A has already occurred.
