A martial artist is practicing breaking 5 boards. He is able to break a board with probability 0.8. (a) What is the probability
that he breaks exactly 2 out of the 5 boards that are placed before him? (b) What is the probability that he breaks at most 3 out of the 5 boards that are placed before him? (c) What is the expected number of boards he will break?
Yes because a triangles are is 1/3 b x h and a rectangles area is just b x h. The triangle would get smaller because it doesn’t have one corner, and the rectangle would keep a constant size.
