An article in Fire Technology, 2014 (50.3) studied the effectiveness of sprinklers in fire control by the number of sprinklers that activatecorrectly. The researchers estimate the probability of a sprinkler to activate correctly to be 0.7. Suppose that you are an inspectorhired to write a safety report for a large ballroom with 10 sprinklers. Assume the sprinklers activate correctly or not independently.(a) What is the probability that all of the sprinklers will operate correctly in a fire?Round your answer to three decimal places (e.g. 0.987).i 0.028(b) What is the probability that at least 7 of the sprinklers will operate correctly in a fire?Round your answer to two decimal places (e.g. 0.98).i!(c) What is the minimum number of sprinklers needed so that the probability that at least one operates correctly is at least 0.98?eTextbook and MediaSave for Later!20F3F4F5MacBook Air品F6Attempts: 0 of 1 usedSubmit AnswerA会AF7F8F9F10F11

Automatic lawn sprinkler systems use a digital system to control the opening and closing of water valves. A sprinkler system usually supports several different zones such as the backyard, left side yard, right side yard, front yard etc. Only one zone's value can be opened at a time in order to remain enough water pressure in the sprinklers in that zone. suppose a sprinkler system supports up to 8 zones. Typically, a sprinker system is controlled by a small, inexpensive microprocessor executing a program that opens each value only at specific times of the day and for specific durations. suppose the microprocessor only has 4 output pins available to control the valves, not 8 outputs as required for the 8 zones. We can instead program the microprocessor to use 1 pin to indicate whether a valve should be opened, and use the 3 other pins to output the active zone (0,1....7) in binary. thus we need to design a combination circuit having 4 inputs, e, and a,b,c (the binary value of the active…
