Probability 0.1 0.3 0.2 0.2 0.1 0.1 which is the expected value of the random variable with the given probability distribution? a. 17 c. 17.8 b. 17.2

Option b 17.2

Step-by-step explanation:

Given is a probability distribution of a random variable say x in table form.We have to find the mean.

All probabilities lie between 0 and 1 and add to 1.

Hence this is a valid prob distribution.

To find mean we multiply the random variable x value with probability and add.

Mean = E(X) =

Hence option b is right answer.
