A class has 21 girls and 12 boys. What is the probability that a boy's name is drawn at random? (5 points)

12/33

Step-by-step explanation:

No.of girls = 21

No.of boys=12

Total no. of students=21+12=33

Probability that a boy's name is drawn at random=12/33

12/33 chance.

Step-by-step explanation:

This problem is solved using the theoretical probabilty formula.  P = probability.  P(Desired outcome).  The desired outcome is pickng a boy's name.  P(Choosing boy's name) = 12(boys)

                                       Total possible outcomes = 33 (boys + girls)

So, in conclusion, 12/33 is the theoretical probablity that you will pick a boy's name.
