B: When a different page is randomly selected and ripped trom the document, it is page 7 a. Determine whether according to the 5% qidere, consider them to be independent) b. Find PIA and B), the probability that events A and B both occur events A and B are independent or dependent (If two events are technically dependent but can be treated as if they are independent a. Choose the correct answer below O A. The two events are independent because the oocurrence of one does not affect the probability of the O B. The two events are independent because O C. The two events are dependent because the oocurrence occurrence of the other the 5% guideline indicates that they should be treated as independent he occurrence of one does not aftect the probability of the occurrence of the other O D. The two events are dependent because the occurrence of one affects the probability of the occurrence of the other

Explanation / Answer

P(A)=1/15 (choosing the 15th page from 15 page book)

probability of B given A ,P(B|A)=1/14 (we have already chosen page 15 now we want some other page which is 7 here)

a) option D is correct because B is dependent on A

b) P(A and B)=P(B|A)*P(A)=(1/14)*(1/15)= 0.00476
