Okay, this is a question on probability.
00:03
The first thing we need to do is find the totals for these this table.
00:09
So there are seven freshmen, ten sophomores, eight juniors, five seniors, and there are four, ten, twelve, thirteen, fourteen total males and seven and six is thirteen and three is sixteen.
00:30
So hopefully both of these add up to thirty.
00:33
I know fourteen and sixteen is thirty.
00:36
So let's check the total on the bottom.
00:38
Seven and ten is seventeen and eight is twenty five and five is thirty.
00:43
Okay.
00:44
Now the question is we want to find the probability one student, one student is picked at random.
00:53
We want to know what's the probability that that student is a female.
00:58
Now that line right there means given which means i know whatever follows it and it says that the person is a junior.
01:12
So like the total possible, you know, you're when you do probability the probability of an event is the number of ways that the event can happen divided by the total ways.
01:33
So like if it had not had this last little part on it, my denominator would have been thirty.
01:42
But this is what i know.
01:45
I know that the person chosen is a junior...
