The AP Exam uses the following relational (comparison) operators: =, ≠, >, <, ≥, and ≤.

Question

As well, AND, OR and NOT are used instead of &&, || and !=.

A comparison using a relational operator evaluates to a Boolean value. For example, a = b evaluates to true if a and b are equal; otherwise, it evaluates to false.

Determine what the following expression would evaluate to.

(9 ≠ 7 AND 17 < 4) OR 65 < 9

yes

true

false

no

Answer 1

The expression (9 ≠ 7 AND 17 < 4) OR 65 < 9 can be evaluated as:

(9 ≠ 7 AND 17 < 4) = (true AND false) = false

(9 ≠ 7 AND 17 < 4) OR 65 < 9 = false OR 65 < 9 = false OR false = false

Therefore, the expression would evaluate to false.
