Answer:
3/5 or 60%
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.
