Chapter 15.5, Problem 6P

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 $p_i=\overline{f\left(x_i\right)}$ Compute the mean, the variance, and the standard deviation for $x$.

Find and plot the cumulative distribution function $F(x).$

A card is drawn from a shuffled deck. Let $x=10$ if it is an ace or a face card; $x=-1$ if it is a 2; and $x=0$ otherwise.
