So uhm, I know this is probably a pretty simple thing but my brain just is fried, I need to find the probability of some particle being in a distance r, with 0<r<a and some others, for the given distribution, now this shouldn't be a problem, I'd've set the integration limits as 0 and a etc. but that would only work with a geq and leq, not a strict inequality, right?

So for the probability a particle is in [0,a] I'd calculate $$\int_0^a |\psi(r)|^2r^2 \dd{r}\dd{\theta}\dd{\phi}$$?

when finding the remainder of a product divided by some integer, say (10 * 9 * 8)/7, why can we find the remainder for each number individually and then multiply them? (1 * 2 * 3 = 6)
