alleryA fair six-sided die is rolled once. What is the probability of getting an even number?
A$\dfrac{1}{6}$
B$\dfrac{1}{2}$
C$\dfrac{1}{3}$
D$\dfrac{2}{3}$
Answer & Solution
Correct answer: B. $\dfrac{1}{2}$
The even outcomes are {2, 4, 6}, so the number of favourable outcomes is 3. The total sample space has 6 outcomes.
$P(\text{even}) = \dfrac{3}{6} = \dfrac{1}{2}$.
