Hi Kate. Very clear, as usual. Thanks!

I however think there is a typo at the end of the post:

P (B1 + B2) = P (C1) + P (B2) - P (B1, B2)

should read

P (B1 + B2) = P (B1) + P (B2) - P (B1, B2)

(the C1 should be of course a B1).

Cheers,

B>

    @lemouth Can't speak for @krishtopa but I want to say thanks. I didn't catch that but was playing with something using her formula and it wasn't working out quite right.
    You'd be surprised to know how often programmers end up making huge mistakes because instead of memorizing equations like this, we look them up and find out only later that our source material had a typo.
    I saw a bank lose $100k because of something similar.
