- What is the probability that the cable selected randomly is too large.
- What is the probability that a randomly selected cable is larger than $1990$ millimeters?
Suppose the manufacturer's specifications for the length of certain type of computer cable are $2000\pm 10$ millimeters. In this industry, it is known that small cable is just as likely to be defective (not meeting specifications) as large cable. That is, the probability of randomly producing a cable with length exceeding $2010$ millimeters is equal to the probability of producing a cable with length smaller than $1990$ millimeters. The probability that the production procedure meets specifications is known to be $0.99$.
