Calculating Total Probability in Hydrogen Atom

[NucEngMajor]

Homework Statement

In general, how would one calculate total probability/ in Hydrogen atom in two different states (n values)?

Homework Equations

P(r) = dP/dr = r^2R(r)^2?

The Attempt at a Solution

That question doesn't even make sense. It's like asking, "How do you calculate the total probability of a pair of dice?"

You calculate the probability of events, e.g., the probability of rolling a 7.
