Transcribed Image Text:Determine whether the events E and F are independent or dependent. Justify your answer.
.....
(a)
E: A person having an at-fault accident.
F: The same person being prone to road rage.
A. E and F are dependent because having an at-fault accident has no effect on the probability of a person being prone to road rage.
B. E and F are dependent because being prone to road rage can affect the probability of a person having an at-fault accident.
C. E and F are independent because having an at-fault accident has no effect on the probability of a person being prone to road rage.
O D. E and F are independent because being prone to road rage has no effect on the probability of a person having an at-fault accident.
(b) E: A randomly selected person planting tulip bulbs in October.
F: A different randomly selected person planting tulip bulbs in April.
A. E cannot affect F and vice versa because the people were randomly selected, so the events are independent.
B. E cannot affect F because "person 1 planting tulip bulbs in October" could never occur, so the events are neither dependent nor independent.
C. E can affect the probability of F, even if the two people are randomly selected, so the events are dependent.
D. E can affect the probability of F because the people were randomly selected, so the events are dependent.
E: The rapid spread of a cocoa plant disease.
