Question

A teacher randomly selects students to write the date on the board each day. There are 12 boys and 9 girls in the teacher's class.

The probability the teacher chooses a girl to write the date on the board, written as a fraction, is?

Answer 1

So there are 12 boys and 9 girls right?

The fraction would be 9/21

9/21 would equal 3/7

So in this case 3/7 would be your final answer, Hope it helps.

Answer 2

`(3)/(7)`

Explanation:

We have 12 Boys and 9 girls, which make up a total of 21 Students.

Out of this total, we are asked to write the probability of a girl writing the date on the board.

Hence, the answer would be the Number of Girls in the classroom / Total


=
`(9)/(21)` =
`(3)/(7)`
