So in this one in part a, we want the probability of being female and 16 to 24.
00:07
That's the intersection of the row in the column of female in 16 to 24, which is 0 .061.
00:16
B, we want the probability of being 16 to 54.
00:21
Well, that's adding up all the ones from 16 to 54, which is 0 .128 plus 0 .6 .6.
00:32
38, which is .7666.
00:38
C, we want the probability of being male or 25 to 54.
00:52
Well, that's the probability that we're male, plus the probability they're 25 to 54, minus the probability they're both, this is the intersection of the row and the column for those.
01:04
While being male was .541, being 25 to 55...
