if he study medicine, he will get a good job if he gets a good job, he will get a good wage.he did not get a good wage,therefore he did not study medicine.l validity of the argument using truth table?

Let P represent "He studies medicine."
Let Q represent "He gets a good job."
Let R represent "He gets a good wage."

The argument can be represented symbolically as follows:

P → Q (If he studies medicine, then he gets a good job.)
Q → R (If he gets a good job, then he gets a good wage.)
¬R (He did not get a good wage.)

Therefore, ¬P (Therefore, he did not study medicine.)
