Problem 1
Answer: Independent
The reason why is because each bag is separate from one another, so one event doesn't affect the other. If we know the result of what we pulled out of one bag, it doesn't change the probability of the other event.

Problem 2
Answer: Dependent
Assuming you do not put the first card back, then the probability of picking a King on the second draw will be different than if you picked a King on the first draw. With all 52 cards in the deck, the probability of getting a king is 4/52 = 1/13. It changes to 4/51 after we picked out an ace for the first card (and didn't put that first card back).
Played total n games, and lostcexactly 4:
4:n-4
Let n be one side of the square wood block. Then:
n²=872
n=√872=approx. 30" per side

Number one is A. Two is D and I think three is A ( I'm not entirely sure about the last one)
Subtract the 7 and eliminate the 7 then subtract from 13 on the other side.
