10A - Example 3: Determining the probability distribution for a discrete random variable
Anna, Maddie and Grace try to go out to lunch every Friday. However, on any given Friday one or more of the girls may not be able to make it to lunch. The probability that Anna cannot make lunch is 0.2, that Maddie cannot make lunch is 0.4 and that Grace cannot make lunch is 0.15.
