What is The Probability That The Product is Odd :
Three digits are chosen at random from 1, 2, 3, 4, 5, 6, 7, 8 and 9 without repeating any digit. What is the probability that the product is odd?
- 2/3
- 7/48
- 5/42
- 5/108
Answer: (3) 5/42
Explanation:-
Possible outcomes whose product is odd= 5 X 4 X 3=60
Total outcomes = 9 X 8 X 7
= 504
Then, the probability of that their product is odd = 60/504
= 5/42
Hence, the answer is (3) 5/42
