प्रश्न
The probability of getting an even number, when a die is thrown once is
विकल्प
\[\frac{1}{2}\]
\[\frac{1}{3}\]
\[\frac{1}{6}\]
\[\frac{5}{6}\]
उत्तर
In a single throw of a die, the possible outcomes are 1, 2, 3, 4, 5 and 6.
∴ Total number of outcomes = 6
The favourable outcomes are 2, 4 and 6.
So, the number of favourable outcomes are 3.
∴ P(getting an even number) = \[\frac{\text{ Favourable number of outcomes }}{\text{ Total number of outcomes }} = \frac{3}{6} = \frac{1}{2}\]
