So we're told to fall into events are met exclusive, the probability of you winning a raffle, we'll say: r is equal to 39 percent or we can say 0.39 and the probability of your getting promoted at work will say: p for promotion is equal to 43 percent Or we can say 0.43, and so we want to find the probability that you win the raffle so r or you are promoted to work or for or we can use union so r or p for promotion. So when youse 2 events that are mutually exclusive and you trying to find the probability of 1 or the other occurring, then you can simply just find the sum of the probabilities. And so we can do this with our problem too, because we know that r and p are both mutually exclusive, as we're told in the problem. So, in other words, the probability of r or p is simply equal to the probability of r plus the probability of p. And we know the probability of r is 0.39. The probability of p would to to 0.43, and so, if we add those we get 0.82 or we can just say 82 percent other 1, his work. So the same thing put this right here as our final.
