A pair of dice is thrown then probability of getting sum of numbers on dice is ‘8’, is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → \( \displaystyle\frac{5}{36} \)
Two dice give 6 × 6 = 36 equally likely outcomes. The outcomes with sum 8 are
\( \displaystyle (2,\,6),\ (3,\,5),\ (4,\,4),\ (5,\,3),\ (6,\,2) \)
That is 5 outcomes ((1, 7) is impossible, since a die shows at most 6).
\( \displaystyle P(\text{sum}=8)=\frac{5}{36} \)
