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.
