Hi, i'm david and i'm here to help you answer your question.
00:04
Now let me bring up your question here.
00:07
In the question here we're given the table of the frequency for the gender and the age group.
00:13
So let me go back to your question and check up the portion of your question because i'm not allowed to copy the full question.
00:20
And i will put the table of the frequency on the right here.
00:25
Now in the question a we want to find the probability that the randomly selected driver of fatality who was a male, this will be the given information, was the 15 to the 50, 69 years old.
00:47
So if you find the probability, the age group will be from 55 to the 69.
00:52
Given that, that will be the male.
00:56
So this one here, we will see given the male, so we just see, we will just focus on the male column.
01:03
And this probability equal to the fraction the total male equal to we have to find the total first and it will end up on the mail we have the 299 plus 4671 plus 117 plus 11251 plus 4269 plus 348 then we get equal to the 35 ,678.
01:39
That will be the total number of the male.
01:44
Among the total amount we have the people in the age group of the 55 to the 69.
01:50
It would be the 4 ,269.
01:54
And then we will turn the 4 ,269...
