Question

The probability that Evan purchases a comic book from the bookstore (event A) is 0.67, and the probability that Glen purchases a comic book from the bookstore (event B) is 0.74. The probability that both Evan and Glen purchase a comic book is 0.2442. Given this information, which statement is true?

Events A and B are independent because P(A|B) ≠ P(A).

Events A and B are independent because P(A and B) = P(A) × P(B).

Events A and B are dependent because P(A and B) ≠ P(A) × P(B).

Events A and B are dependent because P(A|B) = P(A).

Answer 1

0.67*0.74=0.4958

Answer 2

events A and B are dependent
