With one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the entire batch is accepted if every item in the sample is okay. a company just manufactured 796 cds, and 205 are defective. if 3 of these cds are randomly selected for testing, what is the probability that the entire batch will be accepted?

0.405224

Step-by-step explanation:

Given :  A company just manufactured 796 CDs, and 205 are defective.

Then, the probability that a CD is defective :

Sample size : n= 3

Binomial probability formula :

By using binomial probability formula, the probability that none 3 CDs is  defective:-

Hence, the the probability that the entire batch will be accepted= 0.405224

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
