Military radar and missile detection systems are designed to warn a country of enemy attacks. A reliability question deals with the ability of the detection system to identify an attack and issue the warning. Assume that a particular detection system has a 0.80 probability of detecting a missile attack. Answer the following questions using the binomial probability distribution:
- What is the probability that one detection system will detect
an attack? If required, round your answer to two decimal
places.
- If two detection systems are installed in the same area and
operate independently, what is the probability that at least one of
the systems will detect the attack? If required, round your answer
to two decimal places.
- If 3 systems are installed, what is the probability that at
least one of the systems will detect the attack? If required, round
your answer to four decimal places.

Military radar and missile detection systems are designed to warn a country of an enemy attack. A reliability question is whether a detection system will be able to identify an attack and issue a warning. Assume that a particular detection system has a 0.93 probability of detecting a missile attack. Use the binomial probability distribution to answer the following questions. a. What is the probability that a single detection system will detect an attack? (to 2 decimals) b. If two...

The automatic opening device or a military cargo parachute has been designed to open when the parachute is 190 m above the ground. Suppose opening altitude actually has a normal distribution with mean value 190 and standard deviation 33 m. Equipment damage will occur if the parachute opens at an altitude of less than 100 m. What is the probability that there is equipment damage to the payload of at least one of five independently dropped parachutes? (Round your answer...

An army depot that overhauls ground mobile radar systems is interested in improving its processes. One problem involves troubleshooting a particular component that has a high failure rate after it has been repaired and reinstalled in the system. The shop floor supervisor believes that having standard work procedures in place will reduce the time required for troubleshooting this component. The time (in minutes) required for troubleshooting this component without and with the standard work procedure is recorded for a sample...
