Observe that for a random variable Y that takes on values 0 and1, the expected value of Y is defined as follows: Upper E left parenthesis Upper Y right parenthesis equals 0 times Pr left parenthesis Upper Y equals 0 right parenthesis plus 1 times Pr left parenthesis Upper Y equals 1 right parenthesis Now, suppose that X is a Bernoulli random variable with success probability Pr (X = 1) = p. Use the information above to answer the following questions. Show that Upper E left parenthesis Upper X cubed right parenthesis equals p. Upper E left parenthesis Upper X cubed right parenthesis = ( nothing times nothing) + ( nothing times p)= nothing (Use the tool palette on the right to insert superscripts. Enter you answer in the same format as above.)
