Question

​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.

Answer 1

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

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.
