A glass vase factory recently produced 3 vases that were chipped and 12 vases that were not. What is the experimental probability that the next vase will be chipped?
3+12=15 which is the total number of vases. 3 out of 15 vases were chipped so the probability that the next vase will be chipped is 3/15 or 1/5 or 20%.
