I think C.
A: Revenues are irrelevant to the looseness of the slot machines.
B: In this option slot machines are being compared to other games- but we have to compare the slot machines at X v/s Y.
D: Irrelevant - which casino has which type of machine -> we have to just ensure that she puts her money in the loosest slot machine -> And the passage already says that the $5 slot machine is loosest in Y (so even if X has a $5 slotmachine it will not change anything)
E: This still does not tell us that putting her money in Y and not in X was a better choice.
C: This gives her the strongest support if Y is the one that is truthful.
Why? There is a 50% chance that casino y is lying so how can i say that she will win

Hi,

Why the answer is B): The logic is basically that if you’re at Casino Y and want to win money, slots are the best bet there. Since Elaine is at Casino Y, this is strong evidence she chose the right avenue.

C) - This would be useful to know yes but if we don't know which casino is providing accurate info and which is not, this doesn't really help us

Hope this helps!

POV for B, do we know what's the footfall at X vs Y? We can't say just that more gamblers winning means she has taken a good decision. There might be 100 times more gamblers at Y than X. The option could be better if proportion was mentioned...Bunuel pls take a look.

I agree with this point. Option B only tells us that more gamblers (in absolute number) win on slot machines at Casino Y, but it says nothing about the percentage of winners. If Casino Y simply has a much higher attendance or more slot players than Casino X, then naturally the raw number of winners would be higher, even if the actual odds of winning are worse.

That’s why I’m struggling to see how (B) provides strong evidence that Elaine made a good decision. The question is about probability of winning, so how does a raw count meaningfully support her choosing a $5 machine at Casino Y?

Revenues are not irrelevant. If Casino Y makes more revenue then it means more players are losing and the odds are against them, hence it does not help the subject with making money.

Casino X advertises that it has the “loosest” one-dollar slot machines in town, which means that the statistical odds of winning money playing a one-dollar slot machine are greater at Casino X than at any other casino. Meanwhile, Casino Y claims to have the loosest five-dollar slot machines in town. In any event, the statistical odds are always against any slotmachine player. Elaine has five dollars to spend on gambling and has decided to play a five-dollar slot machine at Casino Y.

Assuming Elaine hopes to win money, which of the following, if true, provides the strongest evidence that she made a good decision as to how to gamble her money?

(A) Casino Y’s total gambling revenues far exceed those of Casino X.

(B) At Casino Y, more gamblers win money playing slot machines than at any other casino game.

(C) One of the two casinos is providing accurate information about its slot machines, but the other casino is not.

(D) Each of the two casinos has both types of slot machines: one-dollar and five-dollar.

(E) Casino X and Casino Y are the only two casinos in town that claim to have the loosest slot machines of any type.


OFFICIAL EXPLANATION



The correct answer is (B).

Choice (B) provides at least some evidence that the slot machines at Casino Y are “loose” and accordingly that Elaine’s chances of winning at one of those machines is relatively good.

The correct answer is B.
A) This is a trap option. It suggests that Casino Y is more reliable simply because its total gambling revenue is higher, but it does not say anything specific about slot machines. The higher revenue could be coming from other games, which makes this comparison misleading.

B) The concern raised in point A is resolved by this statement. It explicitly says that gamblers are more likely to win money by playing slot machines at Casino Y. This directly supports the conclusion, giving us confidence that Elaine made a sensible decision in choosing how to gamble her money.

C) This creates ambiguity. It is unclear whether Casino X or Casino Y is being dishonest, so no solid conclusion can be drawn from it.

D) This provides additional information, but it has no real impact on the conclusion being evaluated.

E) This option is irrelevant. Like D, it adds extra information that does not affect the reasoning or the final conclusion.
