If you toss a coin three times in a row, it is true that there is only a 1/8 chance that you'll get three heads in a row. But this is confounded by the fact that you're looking at a short sequence. On average, only 14 flips are required to get three heads in a row, and in 100 flips, there's a greater than 99.9% chance there will be three heads in a row at least once.
