What is the probability that the product of two integers (not necessarily different integers) randomly selected from the numbers 1 trough 20, result of multiplication is odd?
A. 1/4
B. 1/2
C. 2/3
D. 3/4
Answer: Option A
Solution (By Examveda Team)
Total integers ; 20even = odd = 10
Since odd x odd = odd and since half the integers 1 to 20 are odd, the probability of selecting two odd integers is 1/2 x 1/2 = 1/4.
