MCQ
If two different dice are rolled together, the probability of getting an even number :
- A$\frac{1}{36}$
- B$\frac{1}{2}$
- C$\frac{1}{6}$
- ✓$\frac{1}{4}$
✓
Answer
Correct option: D.
$\frac{1}{4}$
Rolling two different dice,
Number of total events $= 6 \times 6 = 36$
Number of even number on both dice are $\{(2, 2), (2, 4), (2, 6), (4, 2), (4, 4), (4, 6), (6, 2), (6, 4), (6, 6)\} = 9$
$\therefore\ \text{Probability}=\frac{9}{36}=\frac{1}{4}$
