Question

In a single throw of a die, find the probability of getting a number less than $5$?

Answer 1

When a die is thrown, the possible outcomes are $1,2,3,4,5,6$.

Number of possible outcomes $=6$

$P\left(E\right)=\frac{Numberoffavourableoutcomes}{Numberofpossibleoutcomes}$

Let E be the event of getting a number less than $5$.

Outcomes favorable to E are $1,2,3,4$

Number of favorable outcomes $=4$

$P\left(E\right)=4/6=2/3$

Hence the probability of getting a number less than $5$ is $2/3$.
