Jenny plans to have two children but doesn't know if they will be boy-boy, girl-girl, or boy-girl. What is the probability that she will have two boys?

Choices are A. .5 B. .25 C. .75 D. 1.00

the possibility of the first boy is 1 out of two. The possibility on the second child remains 1 out of 2. so now you have two 1/2. Multiply and you get 1/4
