So we're given this table and a person is going to be selected at random.
00:06
So first we're going to find the probability that they are under the strongly agrees column.
00:13
So in order to do this, we are going to take all of the people who are in strongly agrees, which is 90, because we have a total row and column in this problem, which is really helpful.
00:25
And then we're going to take the total population, which is 224, and divide them.
00:33
So we'll have 90, the total of strongly agrees, divided by 224, which is the total.
00:43
And this gives us 0 .402.
00:50
Now to find the probability, they are in generation x, we do the same thing, but with the row, generation x, instead of one of the columns.
01:02
So for generation x, the total is 23.
01:06
So it'll be 23 divided by the whole population, which is 224, and 0 .103.
01:18
Now, these two are a little bit different...
