Julie performed the experiment of drawing a tile from a bag recording its color and then returning the tile to the bag. She preformed the experiment 20 times and recorded the results. Brown 5. Orange 8. Purple 2. Tan 5. Which color do you predict Julie will not pick next?

I think the answer should be purple. Based on probability. My boyfriend disagrees. I need some help before I send him off to school in the morning.

If it's not a trick question, which it seems like it is,. Then purple would be wrong. Assuming there were the same number of tiles of each color to begin with.

Orange would be least likely picked because it has the most tiles missing already. orange is prolly the answer.

But really you aren't given enough info. I mean you could say "black". And I bet that bitch don't pull out a black one next.

She already did it 20 times. There shouldn't be anymore drawing.

Probability is based off of what you start with in your bag. If you do the experiment and Return the tiles to the bag the probability of pulling colors remains the same regardless of what you've pulled out of the bag. For example lets say you have 20 tiles and 4 colors. If one color is orange and there are 8 orange tiles, then the probability on the first draw of getting an orange tiles is 8/20. If you put that tile back then it's still 8/20 on the next draw. If you leave the tile out then the number of tiles is reduced to 19 and the probability changes. If the tile you first pulled is purple and you leave it out the the probability of getting an orange tile increases to 8/19. Hope this makes sense. I am an engineer who does statistical analysis all the time.
