Question:
In 50 throws of a dice, the outcomes were noted as shown below:
A dice is thrown at random. What is the probability of getting an even number?
(a) $\frac{12}{25}$
(b) $\frac{3}{50}$
(C) $\frac{1}{8}$
(d) $\frac{1}{2}$
Solution:
(a) $\frac{12}{25}$
Explanation:
Total number of trials = 50
Let E be the event of getting an even number.
Then, E contains 2, 4 and 6, i.e. 3 even numbers.
$\therefore P($ getting an even number $)=P(E)=\frac{\text { Number of times even number } s \text { appear }}{\text { Total number of throws }}=\frac{(9+7+8)}{50}=\frac{24}{50}=\frac{12}{25}$
