A pair of dice is thrown, then the probability of getting a sum of 7, is
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 1/6
Two dice have 6 × 6 = 36 equally likely outcomes. The outcomes with sum 7 are
\( \displaystyle (1,\,6),\ (2,\,5),\ (3,\,4),\ (4,\,3),\ (5,\,2),\ (6,\,1) \)
\( \displaystyle P(\text{sum }7)=\frac{6}{36}=\frac{1}{6} \)
