Conditional & Marginal Distributions from Two Way Tables

This problem is from the following book: goo.gl/t9pfIj
Two-way tables can display counts for two categorical variables. In this video, we show first identify the variables and individuals and then calculate a marginal distribution. Next, we calculate a statistics that is part of the conditional distribution (which is the distribution of a variable with one of the other variables values fixed).
