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


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Cookies!

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? wink

Hi;

That's what the calculation is up there. But it is overkill.

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.
