The probability distribution of the size of a random order of hand-sanitizers, X , is as follows: 2 3 4 5 6 Total P ( X =I;) 0. 14 0.2 0.36 0.15 0.1 0.05 1 The expected value is computed, E[X] = 3.02 . Compute the variance and standard deviation: VAR[X]= (Round the answer to 4 decimals) SD[X]= (Round the answer to 2 decimals) Question Help: Video Written Example Message instructor D Post to forum Question 5 0/1 pt 5 3 99 @ Details Leonardo is offered to place a $10 bet on a certain event the probability of which happening is estimated to be 60%. In case of the event occurring Leonardo will receive a total of $25. Let X be the Leonardo's winnings from the bet. Answer the following questions: 1. Create the probability distribution table for X : X outcome payoff x ,$ P(X = x) win loss 2. Use the probability distribution table to find the following: a. E[X] = MX = dollars. (Round the answer to 2 decimal places.) b. SD[X] = ox = dollars. (Round the answer to 1 decimal place.)
