Section 3.1

1.2

(i) EX = 0, $E X^{2} = c^{2}$ , and $Var (X) = c^{2} .$

(ii) $P (| X - E X | \leq c) = P (- c \leq X \leq c) = P (X = - c, X = c) = 1 = \frac{c^{2}}{c^{2}} = \frac{Var (X)}{c^{2}} .$

1.4 If Y is the net loss to the company, then EY = $200, and if P is the premium to be charged, then the expected profit is P − EY = P − 200 = 100, so that P = $300.

1.6 $Var (X) = E X^{2} - {(E X)}^{2}$ by expanding and taking expectations. Also, ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
