Question

A student is chosen at random from a class of 16 girls and 14 boys. What is the probability that the student chosen is not a girl?

Answer 1

Answer:

probability=total number of outcomes-possible number of outcomes

                  =30-16

                  =14

so there are fourteen outcomes of the student choosen is not a girl

Answer 2

The correct answer is $\frac{7}{15}$.

Given: Number of girls in class = 16

Number of boys in class = 14

To Find: Probability that the student chosen is not a girl.

Solution:

Total students = 14 + 16 = 30

Favorable outcome = Student selected is not a girl = Student selected is a boy = 14

Total outcomes = Student selected can be a boy or a girl = 30

P(E) = $\frac{favourable}{total}$

P(E) = $\frac{14}{30}$

P(E) = $\frac{7}{15}$

Hence, the probability that the student chosen is not a girl is $\frac{7}{15}$.
