There are two students. The first,James, will be happy if he solves two problems in a row correctly, the second, Sam, will be happy if he solves the problem correctly only after an incorrectly solved problem. How many days in average James will wait for the "happiness" more than Petya? The probability of correctly and incorrectly solved problems is equal. At first glance, it seems that the answer is 0, since the probabilities are equal, but is this true? Don't think that this task solvesthat easily..

I cannot figure out "WHAT" is this problem asking you to solve! Probably that is ONE of the reasons for "no response".
Please show us what you have tried and exactly where you are stuck.

The English here doesn't make sense. First, who is Petya? But, then, why mention "waiting"? And how many days are they doing this? And how many problems are there per day? I think you are saying that the probability that either of them correctly solves any given problem is 50%; and perhaps the question is, what is the probability that James will be happy more often than Sam? But even that is not a meaningful question.
Please show us the entire original problem, along with a good translation. If you made it up yourself, try again.
