A black and a red die are rolled simultaneously. The probability of obtaining a sum greater than \(9\) , given that the black resulted in a \(5\) is:
- A \(1/2\)
- B \(1\)
- C \(2 / 3\)
- D \(1 / 3\)
Answer & Solution
Correct Answer
(D) \(1 / 3\)
Step-by-step Solution
Detailed explanation
\( P(B+R > 9 \mid B=5) \) \( P(5+R > 9 \mid B=5) \Rightarrow P(R > 4 \mid B=5) \) Possible outcomes for R when B=5: \(\{1, 2, 3, 4, 5, 6\}\) Favorable outcomes for R (>4): \(\{5, 6\}\)…
