Suppose that you throw a fair six-sided die (with an equal probability of getting numbers 1 through 6), and consider two events: (i) the number on the top is an even number (E = {2, 4, 6}) and (ii) the number on the top is three or smaller (S = {1, 2, 3}). What is P(E S), i.e. the probability that the two events happen simultaneously?
