Answer 1

12/33 chance.

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.
