We'Re told the following: 2 events are mutually exclusive. The probability of you winning a ruffle well say: r is equal to 17 percent or we can just say 0.17. We'Re told the probability of getting promoted at work. P is equal to 19 percent or we can say 0.19, and we want to find the probability that you win. The raffle are, or you get promoted at work so or can be represented by union symbols or or or p for promotion. So we want to find the probability of our union p. So when you have 2 events that are mutually exclusive and we know so because they're told so in the problem, then the probability of r or p occurring is simply equal to the sum of their probabilities. In other words, the probability of r p is equal to this probability of r plus the probability of p. And so, if we subbin the values, we know the probability of r is equal to 0.17 and the probability of p is equal to 0.19. And if we add these up, this is equal to 0.36 or we can just say 36 percent either 1 of these works there's the same thing, but this right here is our final abability.
