There are 25 horses, each of which runs at a constant speed that is different from the other horses. Since the track only has 5 lanes, each race can have at most 5 horses. If you need to find the 3 fastest horses, what is the minimum number of races needed to identify them? 5 6 7 8

Let's label each horse 1 - 25. You first need to race each horse: (1, 2, 3, 4, 5), (6, 7, 8, 9, 10), (11, 12, 13, 14, 15), (16, 17, 18, 19, 20) and (21, 22, 23, 24, 25). That is 5 races. Then we take the winner of each heat. Let's say that is the lowest horse number in each heat and race them (1, 6, 11, 16, 21). This guarantees that #1 is the fastest horse. This is the 6th race. Are #6 and #11 necessarily the 2nd and 3rd fastest? No, because it is possible that #2 and #3 just lost in the first heat to the fastest horse (#1). We need a final 7th race between (6, 11, 2, 3, x) where x in any horse.

What are the smallest and largest values that Delta can take for a vanilla put option? Max: -0.5, Min: 0.5 Max: 1, Min: -1 Max: 1, Min: 0 Max: 0, Min: -1

The delta of an option is the 1st derivative of the value of the option with respect to the price of the stock. As stock price increases, the value of a put option decreases thus we know the delta must be negative. The delta for a put can't be lower than -1 because as delta gets closer to -1, gamma (2nd derivative w.r.t. stock price) will go to 0. Also, delta can be interpreted as the probability the option ends up in-the-money, thus a value less than -1 would not make sense.

I toss a coin 400 times. What is the probability of getting < 220 heads? 90% 92.5% 95% 97.5%

Use the binomial distribution. Since p = 0.50 and N = 100, the mean is 50, the variance is 25 and the standard deviation is 5. So 40 corresponds to a one sided 2 std move. A two sided 2 std move contains 95% of the area, so a 1 sided 2 std move contains 95% + 2.5% = 97.5%.

You have a chessboard. From any single diagonal, you remove two square. There are just 62 squares left on the board. You also have 31 domino tiles, each of which is conveniently the same size as two of the chessboard squares. Is it possible to perfectly cover the board with these dominoes, without any domino edges hanging over? Yes No

The opposite corners of a chess board have the same color. Placing a domino on the board requires covering both a white and black square. So, we will not be able to cover the chessboard.

Stock X has an expected return of 5% and stock Y has an expected return of 15%. Stock X has a volatility of 10% and stock Y has volatility of 25%. The correlation between their returns is 25%. What is the allocation to stock X that creates the minimum variance portfolio? 82.50% 90% 93.75% 95%

, and . We recall that the variance of a portfolio with 2 assets is We have thatand. We recall that the variance of a portfolio with 2 assets is To find a local minimum, we need to differentiate, set equal to zero and solve for our parameter . Once you work out the math, you will get that We evaluate the expression with the given inputs. The weight of stock X is 93.75%.

Which of the following is NOT an assumptions of OLS? Exogeneity Spherical errors Normal errors No linear dependence Linear relationship
