let the stochasticaly independent random variable x1,x2
have the same pdf
f(x)=1/6
x=1,2,...,6
find the pdf of y=x1+x2 under appropriate assumption,that
y maybe interprated as the same the spots which appear when two dice are tosed.

Note that y can have the values 2, 3, 4, ...... , 11, 12.

Now use this Dice table to calculate the probability of each of these values.
