Chapter 15.5, Problem 4P

Set up sample spaces for Problems 1 to 7 and list next to each sample point the value of the indicated random variable x, and the probability associated with the sample point. Make a table of the different values $x_i$ of $x$ and the corresponding probabilities $p_i=f\left(x_i\right)$ Compute the mean, the variance, and the standard deviation for x. Find and plot the cumulative distribution function $F(x).$

Suppose that Martian dice are 4-sided (tetrahedra) with points labeled 1 to 4. When a pair of these dice is tossed, let $x$ be the product of the two numbers at the tops of the dice if the product is odd; otherwise $x=0.$
