There are 8 boys and 12 girls in a class.
What is the probability
that a girl is chosen to
do a math problem at
the board?

60% or 3/5

Step-by-step explanation:

12/20

12 girls + 8 boys = 20 total

12/20 / 2/2 = 6/10

6/10 = 60%

3/5 or 60%

Step-by-step explanation:

To find probability, we'll first find the total amount of students in the class. That's 8 boys + 12 girls, or 20 total students. Now, we have to find the probability that a girl will do a math problem at the board. There are 12 girls, so we have to divide 12 by 20 to find our probability.

12/20 is equal to 3/5, or 60%, depending on whether you want to put it in fraction or percentage form.
