A bag has 10 colored chips in it. The colors are red, blue, green, and yellow. By drawing a chips out of the bag and replacing them back into the back, the number of yellow chips in the bag can be discovered. Use this machine to simulate a bag of chips. Press the button to draw a chip. You will need to make 20 to 50 trials to get the correct probablity for the yellow chips.

 
Note: if you click the button and the color does not change then that color was drawn again.

Use a seperate sheet of paper to record the color of chip for each trail. After you have made 20 to 50 trials, count up the total of each different color chip. Place that number over the total trials taken. reduce to simpliest form. Submit the number of yellow chips that are inside the bag.
