 Let's look at the residents of Los Angeles (Angelinos). Suppose 70% of Angelinos bike (B), 30% like ice
 cream (I), and 40% regularly see new movie releases (M). In addition, assume that 15% B and I, 40% J and M, 20% I and M, and 5% like all 3 (B and I and M). Find the probability that a randomly chosen Angelino likes at least one of these three activities.
