Two dice are rolled together. The probability that sum of the numbers obtained is atmost 12, is
A. $1$
B. $0$
C. $\dfrac{1}{2}$
D. $\dfrac{35}{36}$
✅ Answer & Solution
✅ Correct Answer: A
Step 1: Maximum number on each die is 6, so the maximum possible sum is $6+6=12$.
Step 2: "Atmost 12" means sum $\le 12$, which is true for every one of the 36 outcomes.
Step 3: So it is a sure (certain) event:
$$P(\text{sum}\le 12)=\frac{36}{36}=1$$
Answer: (A) $1$
