The table below represents the information above: If we use the probability mass function and summation notation, then we can more compactly write this formula as follows, where the summation is taken over the index i:. In some cases, you may need to assign a value to some or all possible outcomes. Multiply the value of each card times its respective probability. Define all possible outcomes. To use this calculator, a user simply enters in the value of each event or x and the probability of each event or x occurring. You toss a fair coin three times. The values for all six possible outcomes are as follows: What is the expected value of your gain? And this is where I am seeing were I am having problems, what goes where and why?
