Actually it can be done!
Hint: You need two tosses only!!!

if "the first toss is head and second tail" or "both heads" then we take it as head.
Otherwise, we take it as tails.
Will it be correct?

No it wont...
actually the first way will give a probability of p(1-p) + p2
second way will give a probability of (1-p)p + (1-p)2
These are not equal.
But one more hint.... you came so close to the answer and still did not get it correct. I feel bad.. I mean u are really really close!

hmm... i see my mistake.. but from your solution and the way you have written it, i figured out the right answer :D
I hope i am right this time...
tail-head. We call tail
Head-tail. we call head.
But what do we do of the other tow cases i cant figure out.
I mean what if we get head-head. or tail-tail!
