Instructional video shows how to use the distance formula to find the distance between two points. [2:29]

The Pythagorean theorem is useful in solving how to find the missing length of a side of a right triangle. Check out this tutorial to see how it's done. [4:09]

Mean is another word for average. Learn how to determine the mean from a set of data. Watch this tutorial for an example. [3:13]

The median of a data set is the number that is the middle value of the set. Watch this tutorial to learn how to find the median even if there are two middle values. [3:52]

The midpoint of a line segment is the point midway between the endpoints of the line segment. This tutorial shows you how to find it. [2:23]

View this tutorial and see how to figure out the probability of independently drawing certain cards from a deck. [5:54]

This video describes the process for finding the overall probability of drawing certain cards from a deck when the two events are independent, i.e., have no impact, on each other. In the example presented, one card is a queen and the other is less than seven, and their probabilities are used to calculate the probability of both happening. [5:53]

Using a card trick as an example, this tutorial explains how to find the probability of independent events. [5:53]

Probability is the likelihood that a given event will take place. So how do you determine the probability of a simple event? Watch this example using marbles for an explanation. [4:36]

Probability is useful when solving everyday problems. Watch this tutorial to see how to find the probability of the complement of an event using gummy worms. [5:36]

The complement of an event is the set of all non-favorable outcomes. Watch this demonstration to understand how to find the complement of an event. [5:36]

You can use the formula for the area of a circle to find the radius. This tutorial shows you how to use that formula and the given value for the area to find the radius. [3:28]
