Okay, and this problem we have that this owner is building on two projects a and b, and the probability that he wins a is 30, probability that he wins b is 40, and they're independent events.
00:15
All right, their independent events.
00:16
They have nothing to do with each other.
00:17
Now, if they are independent, then that means that the probability that they both happen is their product.
00:24
So that's the first thing that we need.
00:26
The probability of a intersect b is going to be equal to probability of a times the probability.
00:32
Of b.
00:33
So that's going to be important because 0 .3 times 0 .4 is going to give us, well, i'm not entirely sure.
00:39
I think it's 0 .07, but let me make sure.
00:41
Point 3 times 0 .4 is going to be 0 .12, of course...
