Okay, we have here two events.
00:03
A, the student is a man, b, the student belongs to a sorority.
00:09
First thing, of course, what does that mean? well, on definition, this is a female club.
00:19
So only girls are allowed to join this particular club.
00:27
So, no way can a man be in the female club.
00:30
Which means they are going to be mutually exclusive.
00:36
So just define that one moment.
00:39
Mutually exclusive implies two events cannot occur at the same time.
01:01
For example, we take one card from a pack of playing cards, that one card can't be a king and the queen at the same time.
01:12
Therefore, those two events are mutually exclusive.
01:15
But the card could be a king and a heart at the same time.
01:20
Those two events are not mutually exclusive.
01:23
So here then we also have p of a and b will be zero.
01:32
There's no overlap between a and b...
