Question

A classroom has 28 students, 11 of these students are boys. If a student is randomly

chosen, what's the probability that the student will be a girl? Round

Answer 1

Probability that student will be a girl = 17 / 28

Explanation:

Given:

Total number of student = 28 student

Number of boys in the class = 11

Find:

Probability that student will be a girl = ?

Computation:

⇒ Number of girls in class = Total number of student - Number of boys in the class

⇒ Number of girls in class = 28 - 11

⇒ Number of girls in class = 17

⇒ Probability that student will be a girl = Number of girls in class / Total number of student

⇒ Probability that student will be a girl = 17 / 28
