To start off,

First calcultae:

How many ways you can select 3 people (boy or girl) out of the given 10 people.

Please share your work with us, indicating exactly where you are stuck, so that we may know where to begin to help you.

 
thank you

To show my work: I am not sure if i am correct
I would have BG, GG, GB, BB = 0x1/4+ 1x1//2+2x1/4=1
I don't know where to go from there
 
combination probability

never mind the previous post, I used the combination probability 1oC3= 120
