Determine whether the events e and f are independent or dependent. justify your answer. (a) e: a person going into debt. f: the same person having a credit card. a. e and f are independent because going into debt has no effect on the probability of a person having a credit card. b. e and f are dependent because going into debt has no effect on the probability of a person having a credit card. c. e and f are independent because having a credit card has no effect on the probability of a person going into debt. d. e and f are dependent because having a credit card can affect the probability of a person going into debt.

D

Step-by-step explanation:

We say that two events A and B are independent when the probability that event A occurs has no effect on the probability that event B occurs. On the other side, A and B are dependent when the outcome of A actually affects the probability of the occurrence of B.

In this problem the events are:

In this case, we know that when one person has a debt, the probability that the person gets a credit card approved is affected (it is less probable). Also, a person that has a credit card has more probability of going into debt because of it.

Therefore, these 2 events are dependent because having a credit card can affect the probability of a person going into debt.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
