Question

The probability of Samantha scoring an A on a geology test (event A) is 0.46, and the probability of Judith scoring an A on the same test (event B) is 0.54. The probability of both Samantha and Judith scoring an A is 0.2484. Given this information, which statement is true?

Answer 1

Answer:

the statement when the probability of samantha was 0.46 and Judith was 0.54 because the sum of the probability of all events is 1 and when. we add o.46 and 0.54

0.46+0.54=1

is 1 and in the second statement the the sum of their probability is given 0.2484 which is not possible so first statement is true

Answer 2

Answer:

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