So this is a matter of reading the table and just kind of looking at the question carefully.
00:11
You just got to look at the wording.
00:13
That's what's confusing.
00:14
So the first question is what percent of adults surveyed? so you're looking at all adults surveyed.
00:22
You want to, out of all the adults, you want to find the percent that are social media users and in the age group 30 to 49.
00:31
So if you come back here, what i did is social media.

I said yes, age 30 to 49.
00:40
So if you look at that, there's 417 in that group out of the total 1846.
00:48
So that percent is 0 .226 or 22 .6%.
00:54
So if you come back to the first question, it'll be letter a for the first one, 22 .6%.
01:02
That's the percent of adults surveyed that are social media users that are in the age group 30 to 49.
01:10
Okay.
01:11
So if you look, i use the 417 in my numerator and the 1846 in my denominator.
01:20
For the second question, it says what percent of social media users are age 30 to 49? so now you know that you're dealing with only social media users.
01:33
So the social media users is going to be your denominator.
01:38
So for the second question, i have age 30 to 49.
01:42
And this vertical line right here means given that...
