It is found that when a particular 4-sided die is rolled a 1 occurs 26.9% of the time, a 2 occurs 23.8% of the time, a 3 occurs 24.2% of the time, and a 4 occurs 25.1% of the time. Let the random variable X be defined as X = (the number of times that a 2 occurs). If the die is rolled a total of three times: a) Construct a table and histogram for the probability distribution of X. b) Find E(X).
