Assume that X and Y have a discrete joint distribution for which the joint mass function is defined as follows: P( =x,=y) = c|x+y| for x =−2,−1,0,1,2 y=−2,−1,0,1,2
a) Determine the value of c.
b) Compute P( =0,=−2)
c) Compute P( =1)
d) Compute P(|−|≤1)
e) Compute P(=1| =1)
f) Compute (| =1) and (| =1)
