The probability of drawing two aces from a standard deck is 0.0059. We know this probability, but we don't know if the first card was replaced. If the two draws are defined as event A and event B, are the events dependent or independent? A. They are dependent because, based on the probability, the first ace was replaced before drawing the second ace. B. They are dependent because, based on the probability, the first ace was not replaced before drawing the second ace. C. They are independent because, based on the probability, the first ace was replaced before drawing the second ace. D. They are independent because, based on the probability, the first ace was not replaced before drawing the second ace.

A partial proof was constructed given that MNOP is a parallelogram. Parallelogram M N O P is shown. By the definition of a parallelogram, MN ∥ PO and MP ∥ NO. Using MP as a transversal, ∠M and ∠P are same-side interior angles, so they are supplementary. Using NO as a transversal, ∠N and ∠O are same-side interior angles, so they are supplementary. Using OP as a transversal, ∠O and ∠P are same-side interior angles, so they are supplementary. Therefore, __________________ because they are supplements of the same angle. Which statement should fill in the blank in the last line of the proof? ∠M is supplementary to ∠O ∠N is supplementary to ∠P ∠M ≅ ∠P ∠N ≅ ∠P
