A two-page typed report contains an error on one of the pages. Two proofreaders review the copy. Each has 80% chance of catching the error. What is the probability that the error will be identified if
a. each reads a different page?
b. they each read both pages?
c. the first proofreader randomly selects a page to read, then the second proofreader randomly selects a page unaware of which page the first selected.

I still cannot solve it completely. Does anyone have any idea?

Why don't you tell us how far you have got?
