I don't understand what we need to find in this problem...
I mean I don't understand the concept of 'expected'.
Does the answer demand that I count all the possibilities for consecutive heads like in case of occurrence of only one H, there is no possibility of getting a consecutive heads-pair.. And in case of two heads, there's a possibility of 24 because HH can occur at 24 distinct places in the toss .
Am I getting the problem right?
