Translate the following argument and use truth tables to test for validity.

“If 9 is less than 10 and every odd number less than 10 is divisible by 3, then 9 is divisible by 3. THEREFORE If 9 is less than 10 it is less than 10 it is divisible by 3.”

N = “9 is less than 10”

O = “Every odd number less than 10 is divisible by 3.”
