MHT CET · Maths · Probability
If two dice are thrown together. Then, the probability that the sum of the numbers appearing on them is a prime number, is
- A \(1 / 2\)
- B \(3 / 7\)
- C \(5 / 12\)
- D \(7 / 12\)
Answer & Solution
Correct Answer
(C) \(5 / 12\)
Step-by-step Solution
Detailed explanation
Total cases \(=36\)
Prime number are \(2,3,5,7,11\). \(\therefore\) Favourable cases \(=15\)
Required probability \(=\frac{15}{36}=\frac{5}{12}\)
Prime number are \(2,3,5,7,11\). \(\therefore\) Favourable cases \(=15\)
