MCQ
Two dice are rolled simultaneously. The probability that the sum of the numbers on the faces is $9$ is :
- A$\frac{5}{9}$
- ✓$\frac{1}{9}$
- C$\frac{4}{9}$
- D$\frac{2}{9}$
✓
Answer
Correct option: B.
$\frac{1}{9}$
Number of possible outcomes $= \{(3, 6), (5, 4), (4, 5), (6, 3)\} = 4$
Number of Total outcomes $= 6 \times 6 = 36$
$\therefore$ Required Probability $=\frac{4}{36}=\frac{1}{9}$
Number of Total outcomes $= 6 \times 6 = 36$
$\therefore$ Required Probability $=\frac{4}{36}=\frac{1}{9}$
