**Anonymous**, Monday, May 20, 2013 at 4:30amplease answer C part

and answer of

A die has 2 red faces, 2 blue faces, and 2 green faces. It is rolled 240 times. Let R be the number of times red faces appear, and B the number of times blue faces appear.

Consider the random variable D = R - B. That’s D for “difference.” If all 240 rolls show blue faces, then D = -240; if they all show red faces, then D = 240; otherwise D is somewhere in between. The random variable D is the sum of 240 draws at random with replacement from
