In this question we have to find the expected value and the variance.
00:12
We have to find this.
00:14
So, let's we have the table.
00:16
As this is as x and this is as p of x and this is of x into p of x.
00:33
This is x of square into p of x.
00:38
Okay.
00:39
These values are we have to here x 1, 2, 3, 4, 5 and here 6.
00:46
Now, this is 0 .2, this is also 0 .2, this is also 0 .2.
00:55
Here 0 .05, this is 0 .1, this is 0 .2.
01:02
Okay.
01:04
Now, here from here the third part we have this is 0 .15, 0 .45, 1 .35 and the fourth is 0 .1, this is 0 .4, this is 1 .6 and the first one this is 0 .05 and this is 0 .25.
01:25
This is 1 .25 and the sixth part this is 0 .45 and this is 2 .7 and this is 16 .2.
01:34
And in last we sum all these.
01:38
Okay...
