AP EAMCET · Maths · Probability
Two dice are thrown simultaneously. The probability of getting two numbers whose product is even is
- A \(1 / 2\)
- B \(3 / 4\)
- C \(3 / 8\)
- D \(5 / 16\)
Answer & Solution
Correct Answer
(B) \(3 / 4\)
Step-by-step Solution
Detailed explanation
Product of 2 numbers is even if either both are even or 1 is even and 1 odd. Number of ordered pair: for 1 even and 1 odd \(=(\) Selecting 1 odd out of 3 and selecting 1 even out of 3\()\) \(\times 2(\mathrm{a}, \mathrm{b})\) and \((\mathrm{b}, \mathrm{a})\) are difference hence…
