So, in the given question, we have a probability distribution for which we have been asked to compute the value of the, sorry, expected value for the random variable that is x.
00:10
So, this is x and the probability of x, this is 1 .24, 2 0 .27, 3 0 .21 and 4 is 0 .28, right.
00:23
So, this is the probability distribution.
00:25
Now, we know the formula for the expected value, this is sum of x into probability of x.
00:32
So, first we need to compute this value.
00:36
Now, this is equal to 1 into 0 .24, this is 0 .24, then 2 into 0 .27 that is 0 .54, then 3 multiplied by 0 .21 that is 0 .63 and then 4 multiplied by 0 .28 that is 1 .12...
