Hi, i'm david and i'm here to help you answer your question.
00:03
Now let me bring up your question here.
00:06
In the question here we are given the probability distribution function for the random variable x and the question here asks me to find the cumulative distribution function on the x.
00:19
Remind you that the cumulative distribution of the x is equal to the probability in the half the x small is equal to the small x.
00:28
So this will be the small here.
00:30
And for the first value, from the first question a here, when you find the f capital of the x and the value 0, so means that would equal to probability the x will be smaller than equal to the 0.
00:44
It can equal then the x can equal to minus 2, x can equal to the minus 1, and x can equal to the 0.
00:54
So therefore we have the corresponding probability for the minus 2.
00:58
Will be the 0 .22 and the minus 1 will be the 0 .119 and at the 0 .24.
01:07
If we add them up, we have the 0 .22 plus 0 .19 plus 0 .24 equal to the 0 .65...
