Flipping Coins
- Think about the
distribution of coin flips and their probability. For H assign a value
1, for T, a value of -1. Now considering what you remember about the
properties of the distribution (do not perform any calculations or coin
flips), predict your score after:
- 1 flip
- 2 flips
- 4 flips
- 10 flips
- 100 flips
- Now calculate the standard deviation for the above cases. You
may have to calculate this for 1, 2, and 4, but seeing the pattern that
is emerging, can you make a reasoned guess for 10 and 100.
