Question: 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

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 0.7 while that of B and C are 0.7 and 0.8 respectively. Assume these events are independent. Do not round results. What is the probability that 1. all 3 machines will break down? 2. none of the 3 machines will break down? 3. only machine C will break down? 4. at least one machine will break down? Ev
