1. Roll two dice six times. We are interested in how many times (out of these six rolls) that the sum of the dice equals seven. 

a. Show that this scenario satisfies the conditions of a Binomial Distribution, determine what a "success" is and state what the random variable X stands for.

a. Use =binom.dist(____,  ____ , ____ , false ) to generate the probability distribution.
