I don't really understand how to do this. I thought you would have to take the total number of choices, and basically do 1/3. But none of the answers are 1/3.

anonymous · Answer

No .5 (1/2)

i would say it s a 2/3 but the answer make no scene

anonymous · Answer

It wouldn't be 2/3 because there is only one out of three for a boy-boy outcome.

Well, there are 3 possible ways of having children, and having 2 boys is (only ) 1 way out of the 3 ways.

So the probability is ?

anonymous · Answer

1/3, yes, but none of the options are 1/3.

solomonzelman · Answer

Yes, and none of them are evn close, they are 1/4, 1/2 3/4 and 1

Talk to your teacher about this, because   1/3   is 100% correct .
