Question

In the manufacturing of computer memory chips, a company produces one defective chip for every nine good chips. Let be time to failure (in months) of chips. It is known that is an exponential random variable with parameter for defective chip and with a good chip. (where is the last two digits of your registration number. If last two digits of your registration number are 00, use )

i.Analyze the problem to compute the probability that a randomly purchased chip will fail before months of use.

ii.Analyze the problem to compute the probability that a randomly purchased chip will fail after months of use.

HERE MY R=47
