#### DESCRIPTION:

The probability of getting 7 tails in a row is 1/128. How come? We find the probability for EACH tails first. Any particular outcome is 1 out of 128 of the total number of outcomes. What's the probability of getting EXACTLY one heads? Watch the instructor explain starting at 2:20.

#### OVERVIEW:

Probability -Flipping a Coin (Part 2) is a free educational video by Khan Academy.It helps students in grades 7 practice the following standards 7.SP.5,7.SP.8,7.SP.8.a.

This page not only allows students and teachers view Probability -Flipping a Coin (Part 2) but also find engaging Sample Questions, Apps, Pins, Worksheets, Books related to the following topics.

**
1. 7.SP.5 :** Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event..

**
2. 7.SP.8 :** Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation..

**
3. 7.SP.8.a :** Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs..
