Hi, i'm david and i'm here to help you answer your question.
00:03
Now let me bring up your question here.
00:05
In the question here, let me summarize the question behind the diagram here.
00:10
We will have now we have the computers at two plans, one in the texas and the one in the hawaii.
00:22
The texas plan has the 35 employees.
00:26
So we have the 35 employees in the texas and then we have the 25 employees in the texas and then we have the 25 employees in the hawaii so we have the total it will equal to the 60 employees and from here we were going to select the random number 10 employees and now the question i asked you to find the probability that none of the employees in the symbol will come from the hawaii it means that we want to have all of them will be from the texas and then zero will come from the and this one just equal to the proportion.
01:22
The denominator will be the total number of the ways we can choose the 10 employees out of the 60 employees that we will have from the 60 and then we will choose 10.
01:35
And from the top, from the set of the 35 employees from the texas, i will choose 10 of them.
01:41
From 35, i will choose 10.
01:43
And from the 25 employees from the highways i will choose zero of them and if we compute this one we will have 35 choose 10 60 choose 10 get equal to the zupon 0 243 and that's going to be the answer for the part a for the part we want to find the probability that one employee will be from the highway so it means that we have the nine of them will be from the texas and then one will be from the hawaii.
02:20
And this one again just equal to the bottom will be the 60 choose 10 again.
02:25
For the top, from the 35 embrace from the texas, i will choose nine of them.
02:30
From the 25 in place from the highways, i will choose one...
