| Post subject: | I was told there would be no math. |
I'm taking a pre-screening test for a possible job which, much to my annoyance, involves lots of math. I am working through some practice tests but I need help figuring out how to solve one particular word problem: There are 16 jellybeans in a box. 8 are red, 4 are green, 4 are blue. What is the minimum number of jellybeans that must be taken out to ensure that you have one of each color in your hand? I am fucking baffled. Any constructive help is appreciated. Any unconstructive help, if funny enough, will at least be smirked at. |

Zero. You already have one of each color. edit: original wording of question altered. |

The answer is 9. |

Sorry, I was wrong. The answer IS 13. Because you could technically take out all 8 of the Red, then all 4 of the blue. The 13th one would have to be the last color. |

OK. So upon further review, I'm an idiot (not that it was up for review). I had figured 13 too, but when I checked the answer key, it said I was wrong. Of course, it would have helped if I checked the answer key to the test I was actually taking and not the one for a different test.

What was the answer? |

So, do you know why manholes and manhole covers are round? |

| Post subject: | Re: I was told there would be no math. |
The answer IS 13. Here's another one: If 300 jellybeans cost you x dollars, how many jellybeans can you purchase for 50 cents at the same rate? |

150/x? |

It's a question that Microsoft asks/asked potential employees... And the biggest reason I've heard is because a round cover can't fall down a round whole...while a square one could fall down a square hole... |

which is true. com-ed lids are square and require two guys with two manhole hooks to open them. you do not want to drop a 75lb lid into an active com-ed structure....bad things. very bad things... but, the question is flawed because not all manholes, catch basins, and inlets (the concrete structure) are round. and not all frames and grates are round. Most are...but, not all of them. |

why are tables round? Neenah and E.J.I.W. make square structures that have a inset bar that can be removed from the frame, thus preventing a potential drop. the question is still flawed. |

 yes, it is...I actually thought of that. not as much tho, since it is blue above the cloud cover. but isn't blue at night. |

Now I didn't gardiate from some fancy-pants college or anything, but according to the wording, shouldn't the answer be 3? We're taking jellybeans OUT of a box and putting them in our hand, right? Three different colors...the minimum?

the key is the "ensure" you get one of each color. you could draw three reds... |

In fact it says "taken out" which does not imply any limitations on visual assessment of the jelly beans subject to removal from the box. To "ensure" that you get one of each color, you just look at it. |

| Post subject: | Re: I was told there would be no math. |
that is how I understood the question. It also should of mentioned that it was a random draw. Usually the word random and probability questions go hand in hand. I say the answer should be 3 as well |
