• According to data published by the international data security company, Blancco, 27.0% of iPhone 65 devices brought in to mobile carriers and processing companies utilizing Blancco's services between August 1, 2018 and October 30, 2018 were found to have diagnostic issues. If 30 iPhone 6S devices brought in to one of these hundreds of mobile carriers were randomly selected, what is the probability that at least one iPhone 6S will have diagnostic issues?
Tire pressure monitoring system is war in the driver when the tire pressure of the vehicle is 28% below the target pressur. suppose the target tire pressure of a certain car is 32 psi. at what psi will the tea TPMS trigger the warning for this car? suppose tire pressure is a normally distributed random variable with a standard deviation equal to three psi. If the cars average tire pressure is on target, what is the probability that the TPMS will trigger a warning? The manufacturers recommend correct inflation range is 30 psi to 34 psi assume the tires average psi is on target. If a tire on the car is inspected at random, what is the probability that the tires inflation is within the recommended range?

1% of the computers at UMD have been compromised by a cyberattack. DiT has an intrusion detection system (IDS) that raises an alert 97% of the time if a computer is compromised, and does not raise an alert 95% of the time if a computer is not compromised. What is the probability that the IDS raises an alert? number (rtol=0.01, atol=D0.0001) What is the probability that the computer has not been compromised when the IDS raises an alert? number (rtol=0.01, atol=D0.0001)
(a) _3% of customers at the snack counter of a movie theater buy soft drinks. Among those who buy soft drinks, 52% also purchase popcorn. What is the probability that a customer at the counter buys a drink and popcorn? Theaters use this type of calculation to decide which products should be bundled to appeal to customers. Based on the probability so calculated, what is your recommendation whether to bundle the products or not? If the proportion of customer who buys popcorn is 67% . Then find the probability that a customer will buy a popcorn or a soft drink?
Among 8509 cases of heart pacemaker malfunctions, 439 were found to be caused by firmware, which is software programmed into the device. If the firmware is tested in 3 different pacemakers randomly selected from this batch of 8509 and the entire batch is accepted if there are no failures, what is the probability that the firmware in the entire batch will be accepted? Is this procedure likely to result in the entire batch being accepted? The probability is . This procedure is to result in the entire batch being accepted.
