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)
.
