So we get all of this is going to be equal to 2.1. So one way to think about it is, the expected value of x, the expected number of workouts for me in a week, given this probability distribution, is 2.1. Now you might be saying, wait, hold on a second. All of the outcomes here are whole numbers. How can you have 2.1 workouts in a week? What is 0.1 of a workout? Well, this isn't saying that in a given week, you would expect me to work out exactly 2.1 times, but this is valuable because you could say, well, in 10 weeks, you would expect me to do roughly 21 workouts.
