### How many basketballs would fit in this room?

44 réponses↳

Since the position is for a revenue management position, the interviewer will want to see that you can think through the math in a practical way. Don't guess. Instead, think aloud as you work out the answer. Here's a simple way to get a rough estimate of the number of basketballs that will fit in the room. Estimate the size of the room. Let's say it is about 10' x 10', with an 8' ceiling. Now, estimate the volume required for one basketball. To get a rough answer, don't get fancy with equations and dealing with the shape of the basketball. You may not be sure of the diameter of a basketball, but you have a rough idea. To make the math simple, figure that the ball is about 1' in diameter. The ball is the same width in all directions, so it takes up roughly 1 cubic foot of volume. How many cubic feet in the room? 10 time 10 time 8, or 800. So, there's room for approximately 800 basketballs. If I were interviewing a candidate for this type of position, I'd be very pleased if the candidate could think through that answer. But if this were a position for a role that involved more sophisticated math, such as a data analyst or engineering position, I would expect the candidate to go further and discuss how the estimate could be improved. The next step would be accounting for the exact dimensions of the room and basketballs. And an engineer should be aware of dense packing arrangements that could fit more basketballs into the room.

### On the phone was asked two simple probability questions. What is the probability of being dealt a pair of cards? What is the probability of rolling the same side of a dice three times in a row.

6 réponses↳

The reason it is 1/36 is because it does not specify which side it must be. Therefore the first roll does not really count. Once you take the first roll it will decide what you need to roll the next two times. Therefore the math is 1*(1/6)*(1/6)= 1/36. If they asked what is the probability of rolling a 6 three times in a row then it would be 1/216. Moins

↳

Was asked the card question also. For a pair of cards to be dealt from a 52card deck is 3/51. So first card drawn doesnt matter so you have 3 cards out of the 51 cards left that will match the first hence 3/51 as the probability Moins

↳

1/17 and 1/36

### Given two die, what is the probability that the sum when rolled would add up to six?

4 réponses↳

5/36

↳

5/36 is right.... Combinations that add up to six: 1 and 5, 2 and 4, 3 and 3, 4 and 2, 5 and 1. So we have 5 successes. There are 36 individual outcomes because there are 6 sides on each die and 6*6 = 36 So we have 5/36. Moins

↳

1/6

### 100 pennies in a jar. 1 penny has 'heads' on both sides. You pick a penny out of the jar and give it to your friend (without looking at the penny). Your friend flips the penny in the air and gets 7 heads in a row. Which penny do you have? Why?

3 réponses↳

Chance of 1 Heads = .5 Chance of 7 heads in a row = (.5)^7 to do this in your head think of fractions... (1/2)^7 = (1/2*1/2=1/4, * 1/2=1/8, * 1/2 = 1/16....if you do it seven times you get 1/128. so you have a better chance to pick out the penny with two heads (1/100) than to get 7 heads in a row (1/128) Moins

↳

99 times out of 100 you take the normal penny. prob that normal penny give 7 heads in a row is 1/128. so, prob that he has special penny is 1/100 / (1/100 + 0.99*1/128) = 56.2% Moins

↳

~56.4% that you have the 2-headed penny.
