Hi i'm david and i'm here to have you answer your question.
00:04
Now let me bring up your question here.
00:07
Now in this question we are given the three possible event in filling an order.
00:15
So a it will be the divan, the wrong item is sent, b will be the item is locked in the transit, c the item is damaged in transit.
00:25
So we are given the probability of the i equals user ponder 2, probability of the b equals probability of the b equals 0101 and probability of c equals 704.
00:35
And we had to find the probability that unless one of these occurs for the random chosen order.
00:43
So i want to find probability that at least one of a, b, c occurs.
00:56
So by the complement, we can take the total probability minus probability that none of a, b, c occurs.
01:09
And then it means that one minus none here, it remains, and we can write this down as the a, in addition b, in decision c, and all of them will be the complement, and that's what we want to do.
01:22
And then here we should get this one will be, so technically this one should mean the not a, not b and not c, and therefore we can do this one will be one minus we can write this now as a probability of the a union b union c by the complement so let me make sure that none of three of them occurs so we want to have the outside so it means that we want to have the common among the outside so it makes more sense here.
02:14
Okay, and from here because of the common, we write this down as one more, will be one minus.
02:21
Here we have one minus the probability of the a, union, b, union c.
02:27
Then we have here will be 1 minus 1 will be 0, minus, minus will be the plus, so probability a, or b, or c...
