Question

A company manufactures CD drives that theoretically experience disc-read errors 1.2% of the time. If a CD drive is tested for 250 read operations and fails 4 times, the empirical probability that a CD drive will fail is %. If the theoretical model is valid, the company would expect the empirical probability to decrease as the number of read operations .

Answer 1

Let P= error

n = number of operations

P = .016

n = 250

Multiply P and n

.016 (250) = 4

The number of times it may fail is 4.
