What exactly is a probability distribution, and what are the two requirements for a probability distribution?
I am not sure what this means or how to apply it? Any examples that can be given would be great!

Probability distributions describe the behavior of random variables. Informally a random variable is a variable whose values occur by some chance mechanism. Probability distributions describe that mechanism. The cumulative probability function $F(x)=P[X\le x]$ when $x$ is a real number and $X$ is a real valued random variable where $P[X\le x]$ reads as the probability that $X$ is less than or equal to $x$. $0\le F(x)\le 1$ and for any $y
