Question

Let X be a nonnegative random variable (the possible values of X are all nonnegative numbers), and suppose E( X ) = 1, then, the probability that X takes a value greater than 5, cannot be:_________

Answer 1

Larger than 0.2

Explanation:

The random variables are the variable whose outcome depends on the other random events. They usually have possible values with numerical outcomes. The X = 1 then the probability that X takes value higher than 5 is not larger than 0.2 They are used in regression analysis and their value is subject to variation.
