I want to know how to approach this, my lectures are way too confusing and I'm trying to figure out how to do it not just the answer.

1. Western Digital gives the rate of non-recoverable read errors per bits read of its 8 TB WDSOEFZX hard drive as less than 1 in 10\". Suppose such a drive is full. What can you say about the probability of encountering at least one non-recoverable read error while copying the entire drive, based on this information? a. Give the exact answer and explain it. Consider that hard drive manufacturers use decimal, not binary prefixes in their capacity specifications, La. 1 TB is one trillion (1012) bytes. b. Give a decimal approximation of the probability in a. using the calculus fact that 11. (1+3) we\" for small le and large integers n. You may give your answer as a percentage
