Based on the dartboard shown below, what is the probability of a random throw hitting a section that is yellow or 1?

Since the events are mutually exclusive (you can't hit a yellow section and 1 section at the same time), we can add the probabilities of both A (hitting a yellow section) and B (hitting a section with a 1).




Thus, the probability of hitting a yellow section or a section with a 1 is .

However, if the workers do outside of what's normally expected, go ahead and tip.
