Using it's concept, it is found that a good estimate for the probability of drawing out a green block from the bag is of 0.67 = 67%.
What is a probability?
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, to get a good estimate, we get the probability taking the outcomes from the sample, that is, 67 green blocks out of 100 blocks, hence:
p = 67/100 = 0.67.
A good estimate for the probability of drawing out a green block from the bag is of 0.67 = 67%.
