A c ∩ C = { orange, yellow, purple } WebbThe intersection of two sets A and B, denoted A ∩ B, is the set of elements common to both A and B. In symbols, ∀x ∈ U [x ∈ A ∩ B ⇔ (x ∈ A ∧ x ∈ B)]. The union of two sets A and B, denoted A ∪ B, is the set that combines all the elements in A and B. In symbols, ∀x ∈ U [x ∈ A ∪ B ⇔ (x ∈ A ∨ x ∈ B)].

WebbNow find the probability that the number rolled is both even and greater than two. Solution: In both cases the sample space is S = {1,2,3,4,5,6} and the event in question is the intersection E ∩ T = {4,6} of the previous example. Since the die is fair, all outcomes are equally likely, so by counting we have P(E ∩ T) = 2.
