Question

A prefect is to be chosen from 15 girls and 8 boys. What is the probability that the prefect is a girl?​

Answer 1

Probability = 15/23

Explanation:

Now we have to,

→ find probability that prefect is a girl.

The total members are,

→ 15 girls + 8 boys

→ s = 15 + 8

→ [ s = 23 ]

Then the probability will be,

→ P = 15/s

→ [ P = 15/23 ]

Hence, the answer is 15/23.

Answer 2

• 0.6522 or 65.22%

Explanation:

Total number of candidates is:

• 15 + 8 = 23

Probability of a girl to be chosen as prefect:

• P(girl) = number of girls / total number of candidates

• P(girl) = 15/23 = 0.6522 or 65.22%
