#### DESCRIPTION:

Up until now we've looked at probabilities surrounding only equally likely events. What about probabilities when we don't have equally likely events? Say we have unfair coins?

#### OVERVIEW:

Probability without equally likely events is a free educational video by Khan Academy.It helps students in grades 7 practice the following standards 7.SP.6,7.SP.7,.

This page not only allows students and teachers view Probability without equally likely events but also find engaging Sample Questions, Apps, Pins, Worksheets, Books related to the following topics.

**
1. 7.SP.6 :** Approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability. For example, when rolling a number cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not exactly 200 times..

**
2. 7.SP.7 :** Develop a probability model and use it to find probabilities of events. Compare probabilities from a model to observed frequencies; if the agreement is not good, explain possible sources of the discrepancy. .
