what is the probability of flipping 3 coins and getting exactly 1 head?
how is it so though?
let say 3 coins A B and C. among the 3 coins any 1 can show head. for each coin, probability of getting head= 1/2, and probability of getting tail=1/2. therefore probability=P(head) x P(tail)xP(tail) = 1/2 x 1/2 x 1/2 = 1/8. lolz sorry it should be 1/8.
And I think that the coins are all flipped at once without considering the orders of flipping the coins. therefore we don't need to multiply the probability by 3.
my computer quiz said it was 3/8.
then I think the question should be asking to flip the coins one by one rather than flipping the coins all at once. so in this case it could be A be head, or B be head, or C be head. So just take the probability I found multiply by 3 where u get 3(1/8) = 3/8
