Question

In a class of 10 students 4 are boys and the rest are girls. the probability that a student selected will be a girl is.

Answer 1

Answer:

Probability = No of favourable events / Total no of events

No of favourable events (no of girls ) = 10 - 4= 6

Total no of events (no of students) = 10

Therefore probability = 6/10 = 3/5

Answer 2

Given,

In a class of 10 students 4 are boys and the rest are girls.

To Find,

The probability that a student selected will be a girl is =?

Solution,

We can solve the question as follows:

It is given to us that in a class of 10 students, 4 are boys and the rest are girls. We have to find the probability that a student selected will be a girl.

$Total\: number\: of\: students = 10$

$Number\: of\: boys = 4$

$Number\: of\: girls = 10 - 4 = 6$

Now,

The probability of an event is given as the number of favorable outcomes divided by the total number of outcomes.

$Probability = \frac{Number\: of\: favorable\: outcomes}{Total\: outcomes}$

To find the probability that a student selected will be a girl,

$Favorable\: outcomes = 6$

$Total\: outcomes = 10$

$Probability = \frac{6}{10} = \frac{3}{5}$

Hence,  the probability that a student selected will be a girl is 3/5.
