PROBLEM $3$

The domain of discourse for this problem is a group of three people who are working on a project. To make notation easier, the people are numbered $1,2,3.$ The predicate $M(x,y)$ indicates whether $x$ has sent an email to $y,$ so $M(2,3)$ is read "Person $2$ has sent an email to person $3."$ The table below shows the value of the predicate $M(x,y)$ for each $(x,y)$ pair. The truth value in row $x$ and column $y$ gives the truth value for $M(x,y).$
