### 25 horses, 5 race tracks. How many races you have to run to select top 5 horses.

51 réponses

The answer is 9. Assuming: - There's no time measuring (stopwatch), just relative places. - The horses perform consistently. - A maximum of 5 horses per race. First we need 5 races (A to E) to get relative scores for all 25 horses. Let's take a worst scenario: the list was already ordered (A1 fastest and E5 slowest), so race A contained the top 5. The 6th race would be the winners of the 5 races (A1, B1, C1, D1, E1), and would give A1 as the fastest of all. This would also mean that some horses can be excluded (only 4 more places to fill): B5 C4, C5 D3, D4, D5 E2, E3, E4, E5 For the 7th race, A2 would replace A1, and A2 would be appointed as the runner-up (of all). We also can exclude some more (only 3 more places to fill): B4 C3 D2 E1 For the 8th race, A3 would replace A2, but as E1 has been excluded, we got a vacancy. Let's add C2 for worst case scenario. The winner would be A3, and we can exclude more horses (only 2 more places to fill): B3 C2 D1 At this point there're only 5 horses who have not yet been classified or excluded, so the winner and runner-up of the 9th race would give 4th and 5th overall. Moins

You guys are not doing CS! 10 runs is my answer. 1. randomize 5 groups, each of 5 horses 2. rank them within each group, I will use Anuradha's notation (5 races) 3. pick the best of each group, race to figure the 1st place, call it A1 (1 race) It should be clear, it wins all times, every one lost once. 4. remove it. substitute 2nd best in. repeat 3 (in my eg. A2,B1,C1,D1,E1) now you have second place. keep going, you get the first 5 and ranking! So, 5+5=10 races in total. Moins

Anuradha's solution still has problems. (Even if we go with Anuradha's assumptions that you can only race one horse per track, and also assuming that we don't have a stopwatch and must compare horses placing positions) What if the fastest five horses are A1, B1, C1, D1, and E1 ? In Anuradha's second step, he elminates two of the fastest horses (D1 and E1) . He's assuming that A2, B2, or some of the other horses from the other heats are faster, but he hasn't actually tested to see if that is true. Moins

I also interviewed at the LIC headquarters on October 5th 2015 and got an email that ask for DOB and SS# and there was an email stating that there was an issue with the link that was given and that we should wait for the next day which would've been Oct 9th. Then just yesterday Oct 21st I got the email stating they got my info and that they appreciated my patience in this matter.. So I'm sure it's just a matter of time for the background check to happen Moins

### You have the choice between using first class or third class mail for a letter you are sending out to potential customers. First class costs \$0.50 per piece and reach 100% of potential customers. Third class costs \$0.40 per piece and reaches 80% of potential customers. Which do you use?

10 réponses

either one is good. For example, you will reach 0.8 person by spending \$0.4. If divided 0.4 by 0.8, we get that we will reach 1 person by spending \$0.5. So two methods have the same effect. Moins

First class should be used, as the cost of each delivered letter will be the same, but you will reach all of your intended audience. Example: 1000 pieces to be sent, sending first class costs \$500 and reaches 1000 (\$.50 per peice), and sending second class costs \$400 and reaches 800 (\$.50 per piece) Moins

@gaurav: don't make it too complicated. they just want to know the costs of reaching the customers. peppermint is right. Moins

### Pretend 1% of the population has a disease. You have a test that determines if you have that disease, but it's only 80% accurate and 20% of the time you get a false positive, how likely is it you have the disease.

8 réponses

You don't need the test. The answer is given... 1% of the population has the disease... Answer: 1% Moins

1%. The first sentence gives you all the info you need.

1% chance if using global population. Chances would decrease or increase depending on certain variable or demographic factors so I would say you need more data to give a specific answer. Things like age , gender , race , need to be taken into consideration if you are a 33 year old male and the subject disease is ovarial cancer then you have 0 percent chance . If you are a 40 year old nun and the disease is The clap you have less probably of being infected than say a 26 year old prostitute .. Moins
