Probability — a probability from a discrete joint distribution

Two random variables XX and YY have a discrete joint distribution given by

P(X=x,Y=y)={c∣x+y∣,x,y∈{−2,−1,0,1,2} 0,otherwiseP(X=x,Y=y)=\begin{cases}c|x+y|, & x,y\in\{-2,-1,0,1,2\}\ 0, & \text{otherwise}\end{cases}

What is P(∣X−Y∣≤1)P(|X-Y|\le1) equal to?
