Question

There are 12 boys and 13 girls in a class. If the teacher randomly chooses a student's name out of a hat, what is the probability it will be a girl?

Answer 1

The probability of getting a girl's name is $52%$ percent.

Probability

Probability deals with the occurence of a random event and  is calculated by dividing the total number of events by the total number of possible outcomes.

How to find the probability of getting a girl's name from the mixed students?

First, find the possible outcomes.

In the class, there are $12$ boys and $13$ girls.

The teacher randomly chooses a student's name out of a hat.

So, the possible outcomes $=(12+13)=25$

Let, $S$ be the sample space.

Then, $n(S)=25$

Let, $E=$the event of getting a girl's name

Then, $n(E)=13$

Let, $P$ be the probability of $E$.

Then, $P(E)=\frac{n(E)}{n(S)}=\frac{13}{25}=52$ percent.

Hence, the probability of getting a girl's name is $52$ percent.
