Yep, and there could be no fives or 4 fives before. Point is, we can say nothing about the 14 cards above.

Lets rephrase the original cookies question in a different way. Suppose the 14 cookies are lined up in a row. What is the probability that the 7th cookie from the left is a chocolate-chip one?

Isn't it just 6/14 =3/7 ?

That's right! The other methods produce that answer too. If you program it you will get the same answer. They just are not necessary.

I thought you were going to say he could be a tough cookie.
