We'Re told the following: 2 events are mutually exclusive, the probability of winning a raffle will say are where tota is 30 percent or we can say 0.3. The probability of your getting promoted at work will say p for promotion, actually that's kind of redundant p of p. Let'S just say, let's say w for work is equal to 32 percent or we can say 0.32 and were asked to find the probability that you win. The raffles are or you get promoted or can be written by the union. Symbol like this, so r or promotion at work so wont, so we want to find the probability of our union win. So when you have 2 events are and w in our case, which that are mutually exclusive, and we know that's true, because we're told so in the problem that the probability of 1 event or the other event occurring is simply just a sum of the 2 probabilities. In other words, the probability of our union w is equal to the probability of r plus the probability of wont, and so, if we just sub in the values we know, we know the probability of r is 0.3. The probability of w is 0.32, and so, if we get us up, this is 0.62 or we can just say 62 percent 1. Other 1 of these works do the same thing, but this is our final answerlity.
