Six faces of an unbiased die are numbered with \(2,3,5,7,11\) and 13 . If two such dice are thrown, then the probability that the sum on the uppermost faces of the dice is an odd number is
- A \(\frac{5}{18}\)
- B \(\frac{5}{36}\)
- C \(\frac{13}{18}\)
- D \(\frac{25}{36}\)
Answer & Solution
Correct Answer
(A) \(\frac{5}{18}\)
Step-by-step Solution
Detailed explanation
The sum of two numbered on a dice is odd only, whence once is odd and second is even. \(\therefore\) Required probability \(=2 \times\) Probability of odd number \(\times\) Probability of even number [ \(\because\) Here, we multiply by 2 because either the even number is on…
