A biology class conducted an experiment to determine whether playing classical music had an effect on the hatching rate of chicken eggs. Here are their results.
Music:
Hatched - 53
Did not hatch - 1
Total - 54
No Music:
Hatched - 37
Did not hatch - 6
Total - 43
Total:
Hatched - 90
Did not hatch - 7
Total - 97
Let event A = Music and event B = Hatched. Are events A and B independent?
a. Yes, P(A) = P(A|B)
b. Yes, P(A) = P(B|A)
c. No, P(A) ≠ P(A|B)
d. No, P(A) ≠ P(B|A)
