Flipping a coin - heads or galley answers - 2
Q1 - 2. If you flipped the coin ten times, you wouldn't expect to see the coin land exactly 5 times on the head and 5 times on the galley, although it might happen. Each flip is a random event. With so few flips in the experiment, it is unlikely to result in exactly half the flips being a head and half the flips being a galley.
Q3 - 4. If you flipped the coin ten thousand times, you would expect to see a head approximately five thousand times a galley about five thousand times. The more flips you do in an experiment, the closer you are likely to get to the theoretical times each event should happen.
If you flipped the coin ten thousand times, you might expect to see a graph that looks something like this:
If you flipped the coin ten thousand times again, you might see a graph similar to the above one or you might see a graph something like this:
Q5. If you had a few weeks to spare and repeated the experiment to flip the coin 10 000 times fifty times, and the results kept looking like FIG 1 above, this might tell you that each side of the coin was not equal. It might also tell you that the way you are carrying out the experiment is not fair and is biased towards Heads.
