An engine manufacturer has observed failures with their product. In the last 6 years, they have experienced 2 engine failures one year, 3 engine failures in two consecutive years, 4 engine failures one year, and 5 engine failures in each of the preceding two years (two in the last month, alone).
The CEO of the engine manufacturer wants to reassure customers. He promises that in the next month, there will not be multiple engine failures (no more than 1 failure).
Assume the probability of failure is exponential.
The CEO asks you to calculate the probability that they are correct: What is the probability there will be no more than a single engine failure in the next month?

An engine manufacturer has observed failures with their product.
In the last 6 years, they have experienced 2 engine failures one
year, 3 engine failures in two consecutive years, 4 engine failures
one year, and 5 engine failures in each of the preceding two years
(two in the last month, alone). The CEO of the engine manufacturer
wants to reassure customers. He promises that in the next month,
there will not be multiple engine failures (no more than 1
failure)....

The manufacturer of a new racecar engine claims that the
proportion of engine failures due to overheating for this new
engine, (p1)(p1), will be no higher than the proportion of engine
failures due to overheating of the old engines, (p2)(p2). To test
this statement, NASCAR took a random sample of 115115 of the new
racecar engines and 165165 of the old engines. They found that 1212
of the new racecar engines and 66 of the old engines failed due to...
