To find the probability of pulling a yellow marble from the bag, you need to determine the ratio of the number of yellow marbles to the total number of marbles in the bag. In this case, there are 3 yellow marbles and a total of 8 marbles. So the probability of pulling a yellow marble is 3/8. ( 2 votes)

For example, the odds are 46.3-to-1 that you'll get three of a kind in your poker hand – approximately a 2-percent chance – according to Wolfram Math World. But, the odds are approximately 1.4-to-1 or about 42 percent that you'll get one pair. Probability helps you assess what's at stake and determine how you want to play the game.
