Answer 1

Answer:

1/2

Step-by-step explanation:

might be wrong with this thinking, but since he already told you he has one boy you just need to look at the probablity that the other is a boy. each kid had a 50% chance. so the remaining kid of unknown gender has a 50% chance of being a boy.

if he did not say one was a boy, it would be 1/2 * 1/2 = 1/4 or 25% that he had two boys

Answer 2

Answer:

1/2

Step-by-step explanation:

We want to find

P( two boys| one is already a boy)

This is really

P( boy)

We know that you can either have a boy or a girl

P( boy ) = possibility of having a boy/ total options

              = 1/2
