I read the official books and used BT instructional videos and the new practice question tool which is a really, really nice addition and I wish it would have been avaiable earlier. I passed 111111 (same strategy for Part 1 and also 1111). However, the material should be updated, especially the...

I've been doing daily exercises with this tool and found it really helpful! Definitely a great improvement. However, I've noticed several times now that Latex code is not displayed correctly which makes formulas really hard to read sometimes.

The way that I like to think about this is that if you own the asset you will mark it to market in your books at the mid-market price. That is, in your companies book / IT system it will show the position at the assets mid-market price. If you now try to sell the asset, however, you will have to...

Just to be clear, P(A AND B) = 0 does not imply mutual exclusivity. An easy counterexample is the intervall [0,1] with the uniform distribution. Let A = [0,1] and B = {rational numbers in [0,1]}. A well known fact is that P(B) = 0. Hence, P( A AND B ) <= P(B) = 0. On the other hand, A AND B = B...

(I am going to get really technical now; this is probably not helpful for anyone trying to study this material for the first time) The point is that P(A and B) = 0 is not the definition of mutual exclusivity. Mutual exclusivity of two event means that their intersection is the empty set, i.e. A...
