Probability and Marble Counting

The video tutorial explains how to calculate the probability of drawing a non-white marble from a bowl containing different colored marbles. It begins by determining the total number of marbles, then explains the concept of probability as the ratio of favorable outcomes to total outcomes. The tutorial concludes by calculating the probability of drawing a non-white marble, which is 17 out of 20.
