Exercise

Exercise 4. American Roulette standard error

The standard error of a random variable $X$ tells us the difference between a random variable and its expected value. You calculated a random variable $X$ in exercise 2 and the expected value of that random variable in exercise 3.

Now, compute the standard error of that random variable, which represents a single outcome after one spin of the roulette wheel.
