In this lesson, you will learn how to solve a probability word problem. Need help with your algebra and geometry? Well...
P(event)= Number of favorable outcomes / Total number of outcomes
In the above problem, the number of favorable outcomes is 4 because there are $ blue marbles in the bag. The total number of outcomes is 12 because there are 12 different marbles in the bag.
A probability can be written as a fraction, a decimal, or a percent. If you choose to write the answer as a fraction, remember to simplify the fraction.
