e: a randomly selected person accidentally killing a spider. f: a different randomly selected person accidentally swallowing a spider. 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 accidentally killing a spider" could never occur, so the events are neither dependent nor independent. c. e can affect the probability of f because the people were randomly selected, so the events are dependent. d. e can affect the probability of f, even if the two people are randomly selected, so the events are dependent.

A. E cannot affect F and vice versa because the people were randomly selected, so the events are independent.

Step-by-step explanation:

Imagine a situation.

We probably live very far from each other

There is a probability that I kill a spider.

There is a probability that you accidentaly swallows a spider.

Or vice-versa.

If I kill a spider, i won't impact the probability that you accidentaly swallows a spider. So these events are independent, and the correct answer is:

A. E cannot affect F and vice versa because the people were randomly selected, so the events are independent.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

the answer is 62.8 cubic units
