With the information given, you can make a list of experimental probabilities.
That is, you can create probabilities based on collected data.
Can you find the remaining experimental probabilities?
Because the bag only holds 10 marbles, you can consider equivalent probabilities out of 10 to help you make predictions.
There are likely to be 2 purple marbles in the bag.
Can you use the same strategy to make predictions for the numbers of orange, yellow, and green marbles?
