(ii) 2 is a prime number and 5 is an even number.
(b) Write down the converse of the following implication.
Hence, state whether the converse is true or false.
Solution:
(a)(i) True
(a)(ii) False
(b) Converse: If x is a multiple of 3, then x is a multiple of 12.
The converse is false.
(c) Premise 2: ABCDEF is a hexagon.
(a) State if each of the following statements is true or false.
(i) 2 × 3 = 6 or 2 + 3 = 6
(ii) 2 is a prime number and 5 is an even number.
(b) Write down the converse of the following implication.
Hence, state whether the converse is true or false.
If x is a multiple of 12,
then x is a multiple of 3. 
(c) Complete the premise in the following argument:
