Please answer! *Will give medal!* Which of the following probability tools would not be a reasonable choice to model the likelihood that Zoe will get a grape gumball from a machine that has 6 different flavors: blue, cherry, grape, lemon, lime, and orange? A) Die B)Spinner D)Slips of paper

OpenStudy (***[isuru]***):

A die.. because the probability of the die is also same

OpenStudy (anonymous):

I would think a die is reasonable because the probability of the die is the same...It says which would NOT be reasonable.

OpenStudy (***[isuru]***):

OPS!! i didn't c that one coming ..lol

OpenStudy (anonymous):

Do you have another answer maybe???....

OpenStudy (***[isuru]***):

mmm im not sure but u may want to have a look at this one openstudy.com/updates/51a49e99e4b0aa1ad887d525‎

OpenStudy (***[isuru]***):

and what abt ur choice (C) ??? it's not here ?

OpenStudy (anonymous):

Honestly they all make sense to me. A spinner could have 6 segments all labeled by each flavor. A die have 6 sides. And you could have 6 papers with each of the names of the flavors and draw one randomly. Ugh I'm panicking this is a really important test.

OpenStudy (anonymous):

Because everyone keeps saying a coin and although that seems like the obvious answer that's wrong because you could use 6 coins or something.

OpenStudy (***[isuru]***):

this is a blind shot.... what would u do if there were more than one gumball from each flavor in that machine... if there was 6 grape one and only one from the rest the probability of getting grape is higher... this difference can't be illustrate by a dice since it has only 6 sides... in a dice the probability of each side is same .... but both in slips of paper and the spinner u can model that difference what do u think ?

OpenStudy (anonymous):

No, I disagree with that because a coin only has 2 sides. And my friend had selected on her test that a coin was the most unreasonable and the result of that was incorrect This question is absolutely ridiculous

OpenStudy (***[isuru]***):

but there r few more arguments... the first one is... even though the above scenario happens there is only 1 result in the end.. you GET the grape or U DON'T GET the grape... whatever happens that's a constant... so whatever happens a coin can represent that model and due to that it's always reasonable to use it.. but if u consider a dice u can't represent that module in a dice ... so if the above scenario happens a dice fails. also the probability of a dice is 1/6 and that of a coin is 1/2 and what ever happens u cant change those 2. But what ever the instance is u can use the coin under the probability U GET or U DON'T but the dice don;t have such a option and there is one more... the coin is already revealed as a reasonable tool because u say that ur friend get it wrong by choosing the coin as answer.. so out of the rest if u sort out the dice is the reasonable answer to me for this question :)
