Our question says that suppose that a batch of 100 items contains 6 that are defective and 9 that are not defective.
00:07
If x is the number of defective items in a randomly drawn sample of 10 items from the batch, find probability that x is equal to 0.
00:16
So our sample size n is equal to 10.
00:20
So the number of defective items, we have 6.
00:22
The number of non -defective items will have 94.
00:25
So the probability of picking a defective item is 6 over 100 that gives us 0 .06.
00:29
And the number of drawn sample from a total of 100 is 10.
00:33
So in this case of us, our probability of success is going to be 0 .06 and our n is going to be 10.
00:42
So our q is going to be 1 minus 0 .06 and that gives us 0 .94.
00:48
So the first question says probability that x is equals to 0.
00:51
That is we should get probability that x is equal to 0...
