If I have a random stack of 5 quarters, the 1st 3 quarters are heads.

What is the probability the the 4th quarter would be another head

What is the probability the the 4th quarter would be a tail

Is there a way to show the probability or odds that you would continue to keep exposing the next in line to be the same as the previous 1,2,3 or 4 verses it being the opposite

P(head) is 1/2 for any coin, no matter how many you have already seen.
