MCQ
Two dice are thrown simultaneously. The probability of getting a doublet is :
- A$\frac{2}{3}$
- B$\frac{1}{3}$
- C$\frac{1}{4}$
- ✓$\frac{1}{6}$
✓
Answer
Correct option: D.
$\frac{1}{6}$
Doublet means getting same number on both dice simultaneously
Doublets $= \{(1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6)\}$
Number of possible outcomes $= 6$
Total number of ways to throw a dice $= 36$
Probability of getting a doublet $=\frac{6}{36}=\frac{1}{6}$
Doublets $= \{(1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6)\}$
Number of possible outcomes $= 6$
Total number of ways to throw a dice $= 36$
Probability of getting a doublet $=\frac{6}{36}=\frac{1}{6}$
