Two dice are thrown simultaneously. What is the probability of getting two numbers whose product is not an even ?
Choose the correct choice from the following:
A) 1 / 2  B) 1 / 4  C) 2 / 3  D) 2 / 5  E) 3 / 7

Rationale: total number of cases = 6 * 6 = 36 favourable cases = [ ( 1,3 ) , ( 1,5 ) , ( 1,1 ) , ( 3,1 ) , ( 3,3 ) , ( 3,5 ) , ( 5,1 ) , ( 5,3 ) , ( 5,5 ) ] = 9 so probability = 9 / 36 = 1 / 4 answer is b
Answer: B
