Deterministic possibilities
All the different possible outcomes.
Random two bit number has deterministic possibilities 00, 01, 10, 11.
Probability distribution
A Probability for each possibility: Pr[x] = p where p \in [0,1]
For a coinflip this would be Pr[Heads] = 1/2 and Pr[Tails] = 1/2
Combine all probabilities for all possible outcomes as vector to get probability distribution+
A valid distribution d has \sum d_i = 1 and for all i is d_i \geq 0
