Hi, I'm wondering if anyone knows if the number of application increase or decrease this year?

So I'm an undergrad there, and as far as I'm concerned, while Bocconi has a 5 top faculty in STR in europe, it really doesn't have the same standing in OT. Actually, it seems like that its presence in OT is just really neglibile (judged by the number of Bocconi professors on google scholar who are interested in OT). Is my understanding correct? Thx!

Hello, everyone! So I came across this rather difficult practice combinations question on magoosh.com, and while the answer was given, the explanation for it was not. Here is the question (and the answer hidden by a spoiler tag): An artist is planning on mixing together any number of different colors from her palette. A mixture results as long as the artist combines at least two colors. If the number of possible mixtures is less than 500, what is the greatest number of colors the artist could have in her palette? (A) 8 (B) 9 © 11 (D) 12 (E) 13 Would anyone happen to know exactly how to approach this question?

Hi everybody, The following question is from Manhattan 5lb : The graph on the left above represents the number of family members per family in Town X,while the graph on the right above represents the number of family members per family in Town Y.The median family size for Town X is equal to the median family size for Town Y. The horizontal and vertical dimensions of the boxes above are identical and correspond to the same measurements. Which of the following statements must be true? Indicate all such statements. A.The range of family sizes measured as the number of family members is larger in Town X than in Town Y. B.Families in Town Y are more likely to have sizes within 1 family member of the mean than are families in Town X. C.The data for Town X has a larger standard deviation than the data for Town Y

The problem: A set of cards is numbered 1 through 5. Which of the two quantities is larger? Quantity A The number of ways to pick 3 of the 5 cards such that card number 1 is included Quantity B The number of ways to pick 3 of the 5 cards such that card number 1 is excluded Official Answer: The total number of ways to choose 3 out of 10 cards is (5!) / (3!)(2!) = 10 Since you have to choose a 1 for Quantity A, the number of ways to choose the remaining 2 out of 4 cards is: (4!) / (2!)(2!) = 6 = Quantity A So the number of combinations EXCLUDING the number 1 must be 10-6 = 4 = Quantity B HOWEVER, I encountered the attached problem and worked through it assuming ordered mattered, as in for Quantity A, if you picked a 1 first, then a 2, and then a 3, it was different from picking a 2 first, and then a 1, and finally a 3. So my calculation for Quantity A was 4*3 (four ways to choose the first card, and three ways to choose the second) = 12 ways to choose two cards, and then multiplied that by 3, because the number 1 could be picked first, second, or third in any of those combinations. For Quantity B, the calculation was merely 4*3*2 because excluding the 1 there are 4 options for the first card, 3 for the second, and 2 for the third. It appears as though the explanation assumes that every group with the same cards are the same no matter what order they were picked in. Is this just a poorly worded question that wouldn't be on the actual GRE? Or what am I missing that indicates that those groups are different? Thanks!
