Question

A math class consists of 25 students, 14 female and 11 male. Two students are selected at random to participate in a probability experiment. Compute the probability that no males are selected.

Answer 1

$\LARGE{ \underline{ \orange{ \bf{Required \: answer:}}}}$

In the die the total no. of students are 25

• Number of possible outcome for no males = Number of possible outcomes for females only = 14

We know that,

∴ P(E) = Number of favourable outcome / Number of all possible outcome

Here we have to find the probability of the event of finding the no. of males.

⇛ P(E) = 14 / 25 (Answer)

And we are done !!

Answer 2

Probability helps us to know the chances of an event occurring. The probability that no males are selected is 0.3033.

What is Probability?

Probability helps us to know the chances of an event occurring.

$\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}$

Given that A math class consists of 25 students, 14 female and 11 male. Two students are selected at random to participate in a probability experiment.

Now, since we need to compute the probability that no males are selected, which can also be taken as the probability of both the students selected are girls. Therefore, the probability can be written as,

Probability = (14/25) × (13/24)

                  = 182/600

                  = 0.3033

Hence, the probability that no males are selected is 0.3033.
