# Simple probability

##

By Khan Academy

In order to find the probability of picking a yellow marble from a bag, we have to first determine the number of possible outcomes and how then many of them meet our constraints.

By Khan Academy

In this example we are figuring out the probability of randomly picking a non-blue marble from a bag. Again, we'll have to think about the possible outcomes first.

# Reading Pie Graphs (Circle Graphs) - Khan Academy

##

By Khan Academy

While pie charts (or circle graphs) are often easy to read they are more difficult to put into percentages since that usually involves fractions. When used to initially teach fractions this process usually is a bit easier. Use the easy to understand video in this learning to explain to students how to read pie charts (circle graphs).

# Probability -Flipping a Coin (Part 2)

##

By Khan Academy

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.

# Probability -Flipping a Coin (Part 1)

##

By Khan Academy

You may have seen the first part of this video on the previous learnboard for common core standard 7.SP.5. If not no worries. :-) This video reviews the probability in a series of coin tosses. Remember that EACH toss is independent so we must multiply each individual probability to find the total.
