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 distribution of the random variable x.
00:10
And let me formulate the table here.
00:18
Now this will be the x and this will be the fx and this will be the cumulative of the x.
00:25
X can take the value of the 1, 2 and the 3.
00:30
And we have the first one will be the 64.
00:34
24 dividing by the 21 and then i'm going the 1 over 4 power under x will be 1.
00:47
So if we compute this one we will have 64 divide 21, it will equal to the 16 over the 21.
01:00
And the next one will have the 64 over 21, 1 over 4 power 2.
01:07
And then we get the 16 divided by the 16 divided 21 will be 4 over the 21.
01:18
And the last one will be the 64 of 21 times 1 over 4 power 3.
01:24
And it will equal to the 1 over the 21.
01:28
And that will be the fx...
