1-70.

Imagine that you have a bag containing 10 marbles of different colors. You have drawn a marble, recorded its color, and replaced it fifty times, with the following results: 9 purple, 16 orange, 6 yellow, and 19 green marbles. Make a prediction for how many marbles of each color are in the bag. Show all of your work or explain your reasoning. Homework Help ✎

What is the experimental probability of drawing each color of marble?

Add up all of the draws.

9 + 16 + 6 + 19 = 50

Multiply by 10 to find the number of each color of marble in the bag. Make sure to round to the nearest whole number.

2 purple, 3 orange, 1 yellow, 4 green.

Divide each number of draws by the total number to find the experimental probability.

$\frac{9}{50}=\text{18 percent purple, }\frac{16}{50}=\text{32 percent orange, }\frac{6}{50}=\text{12 percent Yellow, }\frac{19}{50}=\text{38 percent Green }$
