Random variables and expectation
Distributions, expected value, variance, linearity of expectation.
10 * 1/2
Core
The common distributions
Bernoulli, binomial, Poisson, uniform, exponential, normal, and what each models.
integrate e^(-x^2/2)/sqrt(2*pi) dx from -1.96 to 1.96
Advanced
The law of large numbers and the central limit theorem
Why averages converge and why they are normally distributed.
limit of (1 + 1/n)^n as n -> oo
Statistics measures data; probability theory is the mathematics underneath it. Distributions as functions, expectation as an integral, and the laws that make averages settle down.

Саволҳои маъмул
What is the difference between probability and statistics?
Probability goes from a known model to what the data should look like; statistics goes from data back to the model. Probability theory is the deductive half.
What does the law of large numbers promise?
That the average of many independent samples converges to the expected value. It says nothing about any single trial.
