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?
a. events a and b are independent because p(a and b) = p(a) × p(b).
b. events events a and b are dependent because p(a and b) = p(a) × p(b).
c. a and b are independent because p(b|a) ≠ p(b).
d. events a and b are dependent because p(a|b) ≠ p(b).
