A four-sided die is rolled twice. Let X equal the sum of the two outcomes. Then, the possible values of X are 2; 3; 4; 5; 6; 7 and 8.

A four-sided die is rolled twice. Let X equal the sum of the two outcomes.Then, the possible values of X are 2; 3; 4; 5; 6; 7 and 8. The pmf of X is given byf(x) = (4 ô€€€ jx ô€€€ 5j)=16 for x = 2; 3; 4; 5; 6; 7; 8.Use the Die function (twice) to simulate 1000 observations of X. Plot a relativefrequency histogram with the pmf superimposed.
