A random variable R R\,R represents the number of points scored in a game. Its probability function is:
P(R=r)=r+127r=1,2,3,4,5,6 P(R=r)=\frac{r+1}{27} \quad r=1,2,3,4,5,6 P(R=r)=27r+1r=1,2,3,4,5,6Construct a table giving the probability function of RRR.
Find P(1.6<R<4.8)P(1.6 < R < 4.8)P(1.6<R<4.8)
Construct a table for the cumulative distribution F(r)=P(R≤r)F(r)=P(R\leq r)F(r)=P(R≤r).
