2. A company that produces fine crystal knows from experience that 10% of its goblets have cosmetic flaws and must be classified as "seconds." (a) Among six randomly selected goblets, how likely is it that only one is a second?

0.01875

Step-by-step explanation:

Given that a  company that produces fine crystal knows from experience that 10% of its goblets have cosmetic flaws and must be classified as "seconds."

Let X be the no of seconds.

For any randomly drawn crystal to be as second has a probability 0.10

and this probability is constant for any draw as each crystal is independent of the other

Hence X no of seconds in the sample of 6 goblets is Binomial with n =6 and p = 0.10

Required probability = P(x=1)

=

160
