Using it's concept, it is found that there is a 0.3 = 30% experimental probability of drawing green color.
A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these numbers of outcomes are taken from previous trials.
Researching the problem on the internet, it is found that 15 out of 12 + 10 + 15 + 13 = 50 trials resulted in a green marble, hence the probability is given by:
p = 15/50 = 0.3.
