That's good I missed that.
I thought you were going to say he could be a tough cookie.
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.
Isn't it just 6/14 =3/7 ?
Atlast, I am starting to understand
Let’s 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?
Yep, and there could be no fives or 4 fives before. Point is, we can say nothing about the 14 cards above.
There are many different ways in which it can turn out to be a five.
What information do you have about it? You do not look at the first 14 cards.
Nope. When you have gone down to the fifteenth card you already have the information of the fourteen cards above
