1. What is the probability that product of two integers (not necessarily different integers ) randomly selected from the numbers 1 to 20, inclusive , is odd ?
- A. 1/3
- B. 1/3
- C. 1/3
- D. 1/3
Answer: Option B
Explanation:
Total integers; 20 even = 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.
