A sample of plastic panels was selected and each was tested for shock resistance and scratch resistance. The probability that a panel has high shock resistance is 0.61. The probability that a panel has high scratch resistance is 0.66. The probability that a panel has both high shock resistance and high scratch resistance is 0.45.

a)What is the probability that a panel selected at random does not have high shock resistance?

b)What is the probability that a panel has either high shock resistance or high scratch resistance or both?

c)What is the probability that a panel has either high shock resistance or high scratch resistance but not both?

d)What is the probability that a panel with high scratch resistance also has high shock resistance?

e)What is the probability that a panel has high scratch resistance but low shock resistance?

manufacturer makes integrated circuits that each have a resistance layer with a target thickness of 261 units. A circuit won't work well if this thickness varies too much from the target value. These thickness measurements are approximately normally distributed with a mean of 261 units and a standard deviation of 12 units A random sample of 100 measurements is selected for a quality inspection. We can assume that the measurements in the sample are independent. What is the probability that...

A manufacturer makes integrated circuits that each have a resistance layer with a target thickness of 200 units. A circuit won't work well if this thickness varies too much from the target value. These thickness measurements are approximately normally distributed with a mean of 200 units and a standard deviation of 12 units. A random sample of 16 measurements is selected for a quality inspection. We can assume that the measurements in the sample are independent. What is the probability...
