AI Thread Summary
The discussion revolves around finding the value of a(16), which represents the number of ways to toss a fair coin 'n' times without getting two heads consecutively. Participants express frustration over the lack of constructive dialogue, with some indicating they already know the answer but seek a solution method. Recurrence relations and Markov Chains are mentioned as effective approaches to solve the problem. The conversation becomes contentious, with accusations of condescension and a lack of meaningful contribution. Ultimately, the thread is closed due to unproductive exchanges.

A fair coin is tossed 'n' times. Let a(n) denote the number of cases in which no two heads occur consecutively, then what is the value of a(16)?:woot:

What do you think it is? What are the Relevant Equations? Is this a question from your schoolwork?
 
No...But it involves a good trick (i think) instead of simply rather foolishly counting...:-p

Are you saying that you already know the answer?

Doing it with a recurrence turns out very nicely.

Markov Chains also work pretty nicely.

So what is the point of this thread?

~4% probability.

My point exactly.

I do not appreciate the smarmy answer and if you know the solution then I agree with mfb. What's the point of this thread?

Thus far the point has been "I know something you don't, nyah nyah nyah!" I certainly hope there is more to it soon.

You don't really expect for there to be do you? I think you've already nailed it.

I know the 'ANSWER' but i don't know the 'SOLUTION'...:cool:...and i do hope for a very good method to get it...:wink:...

OK, then this should be treated as any homework problem. So what have you tried?

Nor do I. The OP has earned an infraction for this.
