So in this question, if you're assuming that we have a in a tray, 10 rose beef, 10 m sandwiches, and 5 plus 3 me, sandwiches here, which i'm going to copy.
00:15
We want to know if you consider that we are randomly grabbing six sandwiches from that trail for us and for our five workers.
00:26
Want to find what is the probability that none here, are as from here.
00:35
So in this case, this is given by, because this is the probability, first we divide that by the total number of ways in which we can get six sandwiches out of the 25 that we have available.
00:47
But then we need to specify only those, how many ways that we can get, those six, without having any as the specific type that we don't have in this situation, which is the past track.
01:01
So in this case, we are saying that here we are selecting 6 out of 20 because we are removing those 5 of like that specific type, and we are selecting 0 from that one.
01:15
And that will give us 0 .289, where this here is like the combination form.
01:23
How many ways can we get 6 out of 20? then in item b, we want the probability that you grab 2 of each.
01:32
So in this case, this is given us the denominator is still the same, the total number of ways in which we can get six out of the 25...
