Step 1 - Flip a coin 10 times. Record the number of times Heads showed up.

Step 2 - Flip a coin 20 times. Record the number of times Heads showed up.

1. What was your proportion of heads found in Step 1 (Hint: take the number of heads you observed and divide it by the number of times you flipped the coin). What type of probability is this?
2. How many heads would you expect to see in this experiment of 10 coin flips?
3. What was your proportion of heads found in Step 2 (Hint: take the number of heads you observed and divide it by the number of times you flipped the coin) What type of probability is this?
4. How many heads would you expect to see in this experiment of 20 coin flips?
5. did the proportions differ between our set of 10 flips and our set of 20 flips? Which is closer to what we expect to see?
