Answer:
As the first event outcome affects the probability of the outcomes of the second event, both events are dependant.
Step-by-step explanation:
The events are not independent.
The reason is that the first event affects the outcome of the second event.
This happen because the if we choose a comic book for ourselves, there is a probability of 6-1=5 out of 5+5=10 of getting a comic book for our friend (P=50%).
If we choose a nonfiction book four ourselves, the probability of getting a comic book for our friend is 6 in 10 (P=60%).
As the first event outcome affects the probability of the outcomes of the second event, both events are dependant.

add the times 4+5=9 hours
now divide the two
120/9 = 13.3 km per hour average speed
