Best ResponseYou've already chosen the best response.0Well, I agree that the total number of outcomes for 3 coins is 8. And if only one is heads it could be the first, the second, or the third coin that lands heads. So I agree 3/8 makes sense

Best ResponseYou've already chosen the best response.0So then it would be B wouldnt it? :D

Best ResponseYou've already chosen the best response.0Yes. So doesn't that mean in 100 throws of 3 coins we should have 37.5 times just having 1 head. So in 100 thousand it should be 37.5 thousand. Yes, the answer is B

Best ResponseYou've already chosen the best response.0because 100,000 / 8 * 3 = 37500
