Question

A class has 21 girls and 12 boys. What is the probability that a boy's name is drawn at random? 12 over 21 21 over 12 12 over 33 21 over 33

Answer 1

12 over 33

Explanation:

Since you will be picking a boy and there are twelve boys... twelve is the numerator. For the denominator you would want to combine all boys and girls which equals 33. :)

Answer 2

12/33

Explanation:

To find the probability that a boys name is drawn, we take the boys over the total

We need to find the total

21 girls + 12 boys = 33

P (boy) = boy/total

=12/33
