In the equation, you made the x and E the java games online thing that makes me confused. If the probability of heads as an outcome is. There are 6 elements in the sample space, or 6 possible outcomes that can occur. Sign up using Facebook. If the probability of heads as an outcome is. The value that x takes on in any one roll or coin toss has a known probability. The point here is that my happiness, or utility, is not proportional to my amount of money. MathOverflow Mathematics Cross Validated stats Theoretical Computer Science Physics Chemistry Biology Computer Science Philosophy more Model the game by drawing a ticket out of a box. Then I changed the game. Do you even need independence of events to use linearity of expectation? You could plug that series into Wolfram Alpha to get 2 as your solution. The number of failures k - 1 before the first success heads with a probability of success p "heads" is given by:

# Expected value coin toss

Your computation is correct. An easier way might be to compute the expected winning of each flip separately, and then add them. First flip. So if we were to flip a coin, we expect heads to occur with a probability of.5, or the coin should land as heads half the time. We may not see it. It doesn't always. Chapter 5 DISCRETE PROBABILITY. Example Flip a fair coin three times. The expected number of heads is. 0 ·. 1. 8. + 1 ·. 3. 8. + 2 ·. 3. 8. + 3 ·. 1. 8.
