Assume the number of errors along a magnetic recording surface is a Poisson random variable with a mean of one error every 105 bits. A sector of data consists of 4096 eight-bit bytes. (a) What is the probability of more than one error in a sector? (b) What is the mean number of sectors until an error is found?

Solution:
Assume the number of errors along a magnetic recording surface is a Poisson rand
