There are only 4 remainders possible when dividing a number by 4: 1/4, 2/4, 3/4, or 0.
Taking these remainders and multiplying by 4 equals 4R:
4(1/4) = 1
4(2/4) = 2
4(3/4) = 3
4(0) = 0
The only answer that matches is 0, A.
Am I missing something? What's the OA?

Range of a set of #s = highest # - lowest #
Range before changes = 112 - 45 = 67
Range after changes = 118 - 36 = 82
Difference between ranges = 82 - 67 = 15

y = -1 isn't a solution to the equation since a square root can't be negative. The answer should be 4 (D).

could someone explain why it matters how many different ways the 4 teams can be arranged?
It seems like all that matters is the distribution of the people among teams and not the order of the teams .. or the order of the people on the teams for that matter ..
Thanks for the help in advance.

how does this make any sense either?
"We can rewrite this equation in a base of 3: 3b + 2 = 34, which means that b + 2 = 4 and therefore b = 2."
Thanks for the explanation, if there is one ...

Thanks Cramya. What if after each selection, the ball was replaced? How would that change the solution/answer?

8 consecutive coin flips = 28 possible outcomes?
On page 117 of OG11 (thick orange book) the text reads: "If an experiment consists of 8 consecutive coin flipls, then the experiment has 28 possible outcomes, where each of those outcomes is a list of heads and tails in some order."
Could someone explain how to get to the answer?
