So we're told to fall into events or metal exclusive, the probability of you winning a raffle will say, is 17 percent or we can say 0.17. The probability of your getting promoted at work will say probability, p is equal to 46 percent or we can say 0.46, and we want to find the probability that you win the raffle so r or you get promoted to work so or can be denoted by the Union symbol which looks like this, so our union p for promotion. So when you have 2 events that are mutually exclusive, in our case, we know r and p are both mutually exclusive becase, we're told so in the problem. Then, when you try to find the probability of 1 event or the other occurring on, then you can simply just find the sum of their probabilities. In other words, the probability of r union p, where r and p are both initial exclusive, is simply equal to the probability of r plus the probability of p and so to solve this we can just plug in the values. We know. We know the probability of r is equal to 0.17. The probability p is equal to 0.46 and if so, we add all these up, 0.17 plus 0.46 is equal to 0.63, or we can also write this as 63 percent on either 1 is works. There'S the same thing, but this right here is our final answed. Our final probability,
