In this question we are given with x and f values x are given as 0 1, 2, 3, 4, 5 and the frequency is given as 0 .35.
00:12
I'm sorry, this is given as 70, then 75, 30, 11, 8, 6.
00:22
Okay, so we have to find p of x which is f5 by n.
00:26
And first we have to find n, so n equal to 2 contract.
00:29
So, p of x is 70 by 200 which is 0 .35, then 75 by 200 is 0 .375, 30 by 200 is 0 .15 and 11 by 200 is 0 .055, 8 by 200 is 0 .04 and 6 by 200 is 0 .0 .03.
00:52
The total probability must be 1.
00:53
We check it.
00:54
Then x into p of x we have to find it on.
00:57
That is 0 into 0 .35 is 0.
00:59
Similarly, x y into p of x also we have to find it out which is also 0 .375.
01:07
0 .375.
01:09
Next one, 2 into 0 .15 is 0 .30 and here we will get 0 .60.
01:16
Next one, 0 .165, 0 .495.
01:21
Next, 0 .16, 0 .6 .64...
