in a class of 24 students, 7 have a brother and 9 have a sister. there are 13 students who do not have any siblings. what is the probability that a student chosen randomly from the class is an only - child?

Answer

Explanation:

Step1: Identify total and favorable cases

Total students = 24, students with no siblings = 13.

Step2: Calculate probability

Probability = $\frac{\text{Number of favorable cases}}{\text{Total number of cases}}=\frac{13}{24}$.

Answer:

$\frac{13}{24}$
