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.

answer: i realy don't get it that much can you me figer it out pleas you

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
