Now here we look at a table, right? basically it gives you the distribution of students, right? they live on campus or off campus, a freshman, sophomore, junior, senior, or something like that, right? so first you ask for the probability that student lives off campus is a junior, or live off campus or is a junior, right? so it lives off campus.
00:17
So basically you look at this role and it has to be junior, right? so it's going to be this column, right? so the numbers you have to sum of course is this number, this number, this number, this number, this number, this number.
00:30
This number, oh, you don't have to, so you don't have some this number.
00:33
So that would be, you know, this, so this five numbers put together, right, and divided by the total, which is this, right, so that gives you the property.
00:43
So let's do the sum.
00:45
Then you'll find this, of course, to be 3522 plus 299, 2009, that actually gives you 560, right? 5, 620, or in other words, we can, or in other words, we can simply sum this number and this number, but minus this overlap, right? so that would be the same.
01:10
So i'm going to do this way.
01:11
They give us the same thing, actually, 5, 620 plus 7394, and minus overlapped, that's 2 ,098, and then divided by the total, which is 14907.
01:26
So you'll find the probability actually give by 73%.
01:31
73 .2%, i would say.
01:34
And probably the student lives on campus and is a senior, right? on campus and a senior...
