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
xhas 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
xand column
ygives the truth value for
M(x,y).
