MCQ
The probability of getting an even number, when a die is thrown once, is :
- ✓$\frac{1}{2}$
- B$\frac{1}{3}$
- C$\frac{1}{6}$
- D$\frac{5}{6}$
✓
Answer
Correct option: A.
$\frac{1}{2}$
$S = \{1, 2, 3, 4, 5, 6\}$ there are $6$ possibilities in our set, each number has a probability of $\frac{1}{6}$
$S$ even $= \{2, 4, 6\}$
There are three sets of possibilities
$\text{Probability}=\frac{\text{event set}}{\text{total set}}$
Probability even $=\frac{3}{6}=\frac{1}{2}$
$S$ even $= \{2, 4, 6\}$
There are three sets of possibilities
$\text{Probability}=\frac{\text{event set}}{\text{total set}}$
Probability even $=\frac{3}{6}=\frac{1}{2}$
