Apps M Gmail YouTube Maps A machine operator is considering 3 machines (A, B, and C) that could potentially break down soon. The probability that machine A will break down is 0.4 while that of B and C are 0.4 and 0.8 respectively. Assume these events are independent. Hint: Draw a probability tree/tree diagram. Do not round calculation results. What is the probability that 1. all 3 machines will break down? 2. none of the 3 machines will break down? 3. not all 3 machines will break down? 4. only machine A will break down? 5. only machines C and B will break down
