So we're told the 2 following events are mutually exclusive. The first 1 is the probability of your winning a raffle, so we say the probability of r and we're told the probability of this is 30 percent, or we can also rewrite this as 0.30. Next. The next event is the probability getting promoted at work, so p for promotion will say and that's equal to 49 percent we're to which we can also write is 0.49 and were asked to find the probability that you win the ruffle or or you get promoted, to Work so our union p for promotion, and so we're told that when you're trying to find the probability of 2 mutually slucin events- and we know that because we're told on the problem- the probability of 1 or the other occurring is simply just a sum of the Probabilities, in other words, the probability of r or p, is simply equal to the probability of r plus the probability of p and so the probability of r. We can just save in 0.3, 0 point the probability of p. We can save in 0.49, and so, if you add this up, you get 0.79 or you can just say: 79 percent are then 1 of these works. But this is our final answer and our final probability.
