How do you toss between three?
Generate a random number in [0,1) by flipping the coin, with each flip producing a new binary digit.
- If your random number is in [0, 1/3) take choice 1.
- If it is in [1/3, 2/3) take choice 2.
- If it is in [2/3, 1) take choice 3.
What is the probability that the first flip is heads?

What is the probability of getting at most 3 heads in a single toss of 3 coins?
When 3 unbiased coins are tossed once. And, therefore, n(S) = 8. and, therefore, n(E1) = 1. Therefore, P(getting all heads) = P(E1) = n(E1)/n(S) = 1/8.
How do you find a winner between three people?
