In this question we are given values of x and px.
00:06
So, it will be for x is equal to 1, we have px is 1 divided by 7, 2, 3 divided by 7, 3, 1 divided by 7 and 4, 2 divided by 7.
00:23
So, for the first part, we have p3 is equal to 1 divided by 7.
00:30
Now, the probability density function is the probability calculated at a point.
00:58
Cumulative distribution function is the probability calculated for less than equal to that point.
01:45
So, in the above part, we have the point probability which is also called as probability density function.
02:18
Now, for the second part of the question, we have p1 plus p4 is equal to 1 divided by 7 plus 2 divided by 7.
02:43
So, the value of p1 plus p4 comes out to be 3 divided by 7.
02:53
For the third part, we have p2 and p3 is equal to 3 divided by 7 and 1 divided by 7...
