... For example, suppose that we want to ask what is the probability that, when flipping three coins, we get two heads. Then Ω = {0, 1}3 , P(a) = 1/8 for every a ∈ Ω, we define A as the subset of {0, 1}3 containing strings with exactly two 1s, and we ask what is P[A]. As it turns out, A has 3 elements, ...
