The theoretical probabilities are

Red: 8/20 = 0.4

Blue:6/20 = 0.3

yellow:6/20 = 0.3

The experimental Probabilities are

Red: 11/40 = 0.275

blue: 11/40 = 0.275

Yellow: 18/40=0.45

Both probabilities add to 1 as they should

The yellow is the highest disproportionate answer and it really shouldn't be. If anything it should be red. (0.45 > 0.4 comparing yellow experimental with red theoretical. The yellow is way more than it should be)

The number of trials is double the number of marbles in the jar. The number of trials would be double for each color in the jar. Both blanks are double.
