This is a probability question. Suppose we start our journey from step number 0. We now toss a coin. If the result is a head, we add 3 to a counter. If the result is a tail, we add 2 to the counter. We now move to step number 1. We toss the coin again and depending on the result, we update the counter. We then move on to step number 2 and repeat the experiment and so on. The question is, when we arrive at step 10, what is the probability that the counter reads 23?
