For the given pair of events a and b, complete parts (a) and (b) below. a: when a page is randomly selected and ripped from a 12-page document and destroyed, it is page 12. b: when a different page is randomly selected and ripped from the document, it is page 6. a. determine whether events a and b are independent or dependent. (if two events are technically dependent but can be treated as if they are independent according to the 5% guideline, consider them to be independent.) b. find p(a and b), the probability that events a and b both occur.
