A calculator is composed of four major parts (keyboard, display, processor, power source). For the calculator to function properly, each of the parts must function. Two of the parts have a 0.89 probability of functioning, and two have a probability of 0.73. What is the probability the calculator will function properly? (Round your answer to 4 decimal places.) An industrial cutting tool is comprised of various sub-systems. Consider the following sub-system with two major components: →0.880.88 → Calculate the probability this sub-system will operate under each of these conditions: a. The sub-system as shown. (Do not round your intermediate calculations. Round your final answer to 4 decimal places.) Probability 0.7744 b. Each component has a backup with a probability of .88 and a switch that is 100 percent reliable. (Do not round your intermediate calculations. Round your final answer to 4 decimal places.) Probability 0.8796 x c. Each component has a backup with a probability of .88 and a switch that is 97 percent reliable. (Do not round your intermediate calculations. Round your final answer to 4 decimal places.) Probability
