1. In the game of roulette a metal ball is dropped into a spinning wheel having 38

     compartments, 18 of which are red, 18 are black, and two are green. Suppose we spin

     the wheel ten consecutive times and let a random variable X be the number of times

     the metal ball will land on a red color.                                                                                                                                     

         a. Construct the probability distribution of X.

         b. Suppose you always bet $5 on red. If red shows up you win $5, otherwise

              you lose your bet. What is the probability of

           (i)   making a $30 profit if you bet on ten consecutive spins of the wheel?

           (ii)   breaking even if you bet on ten consecutive spins of the wheel?

     

           (iii) being $5 in deficit if you bet on ten consecutive spins of the wheel?
