probability

Hi, I've been given a task in the class, it goes like this:

A fair coin is tossed n times. Find the probability that the Coin falls on the same side twice...

I've been trying to use Binomial distribution but all I've got is an answer with "n", I don't really have any idea where to start...

I just need tips of which type of probability needs to be used here...

0 on the first toss, 1/2 on the second toss and 1 on the third toss and every toss thereafter.

Do you mean falling on the same side for two consecutive tosses?

Re: probability

Yes, the number of times is 'n'.
