Background Tutorials

Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.

Percents and Decimals are just tools that let us represent numbers, and that is why percents can be converted into decimals, and decimals can be converted into percents. In this tutorial you'll see how quickly you can convert percents into decimals!

Develop a uniform probability model by assigning equal probability to all outcomes, and use the model to determine probabilities of events.

Working with probabilities? Check out this tutorial! You'll see how to calculate the probability of picking a certain marble out of a bag.

Further Exploration

Understand the conditional probability of A given B as P(A and B)/P(B), and interpret independence of A and B as saying that the conditional probability of A given B is the same as the probability of A, and the conditional probability of B given A is the same as the probability of B.

Conditional probability is used to find a probability in all sorts of everyday situations! This tutorial shows you one example of how to find the conditional probability in a real world problem.
