You have a bucket of jelly beans. Some are red, some are blue, and some green. With your eyes closed, pick out 2 of a like color. How many do you have to grab to be sure you have 2 of the same?

If you have two buckets, one with red paint and the other with blue paint, and you take one cup from the blue bucket and poor it into the red bucket. Then you take one cup from the red bucket and poor it into the blue bucket. Which bucket has the highest ratio between red and blue? Prove it mathematically.

If you had an infinite supply of water and a 5 quart and 3 quart pail, how would you measure exactly 4 quarts?

Ans: POUR 3 QUART PAIL INTO 5 QUART.TAKE ONE MORE 3 QUART POUR 2 QUARTS INTO THE ALREADY 3/5 TH FILLED 5 QUART PAIL.EMPTY THE 5 QUART PAIL.POUR REMAINING 1 QUART PAIL INTO THE 5 QUART.FILL 3 QUART PAIL.POUR INTO 5 QUART PAIL.1+3=4.

ANY BETTER SOLUTION PLZ LET ME KNOW

just guesses:

jelly beans = 4
water = fill both pails up to the top and then dump 1/2 of each pail

edit:btw I don't understand your answer, sorry Sad

Ans: 3 quart 5 quart
fill 3 quart....pour into...5 quart pail.>
so 3 quart pail has 3 quarts water
fill 3 quart....pour 2 quarts into 5 quart pail as it can accept only 2 quarts....>
empty 5 quarts from 5 quart pail
pour remaining 1 quart from 3 quart pail into 5 quart pail
fill 3 quart pail...pour into 5 quart pail which has 1 quart in it...total is 4 quarts in this 5 quart pail.

better solutions plz reply.
thanks!

Here is another explanation for the water (even though I like my 1st answer better)

1) Fill up the 3 quart pail and then pour it into the 5 quart pail.

2) Fill up the 3 quart pail again and add it to the 5 quart pail.

3) This leaves you with 1 quart of water in the 3 quart pail.

4) Throw out the water in the 5 quart pail.

5) Add the 1 quart of water in the 3 quart pail to the empty 5 quart pail.

6) Fill up the 3 quart pail and pour it into the 5 quart pail.

Now you have 4 quarts of water
Hope that helps, welcome and good night Very Happy

Thank for the reply...there is nothing which said that you can exactly drop half from each...the bucket might be cone...then how do you exactly remove half?

A similar but different solution for the water problem:

1)Fill up the 5 quart pail and then use it to fill up the 3 quart pail.

2)There are now 2 quarts in the 5 quart pail.

3)Dump the 3 quart pail.

4)Empty the 2 quarts from the 5 quart pail into the 3 quart pail.

5)Fill up the 5 quart pail and then pour out into the 3 quart pail until it is full

There are now 4 quarts left in the 5 quart pail. Pretty much the same method but from a different angle.
