Let's say that you are about to flip an unfair coin where the probability of heads is 0.7. Answer the following questions if you were to flip this coin 10 times.

When flipping the unfair coin ten times, what is the probability that the FIRST success comes after the 7th flip? Notice: This is not exactly geometric distribution but pretty close to it. Geometric distribution goes on infinitely, but this problem only has 10 trials.
