In this problem, we are given that there are two events, a and b, and these two are given to be independent events, where the probability of the event a, that is 0 .5, probability of the event b, this is equal to 0 .3, and we have to first find out the probability that either a or b occurs, which is the probability of a union b.

In the next part, we have to get the probability that that the event a occurs, but b does not occurs, which is represented by this expression.
00:32
And finally, we have to determine the probability that both the events occurs, which is the probability of a intersection b.
00:40
So first we see that these two events are independent events, which means that the probability of a intersection b, that will be equal to the product of the probabilities of the two events.

So we see that this comes out to be 0 .15...
