Answer 2

Question:

A group consists of 5 boys and 15 girls. One of them is selected random. What is the probability that the selected candidate is a girl?​

Answer:

The probability of getting a girl is 3/4.

Given:

Number of boys in the group is 5.

Number of girls in the group is 15.

To find:

The probability of getting a girl.

Explanation:

Total number of girls is 15.

∴ Favourable outcome = 15.

Total number of boys is 5.

∴ Total number of candidates = (15+5)

                                                  = 20.

∴ Total outcome = 20

P(E) = (No. of favourable outcome/ No. of total outcome)

      = (15/20)

      = 3/4.

∴ The probability of getting a girl is 3/4.
