We give you an introduction to probability through the example of flipping a quarter and rolling a die.
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.
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.
Now we're working out the probability of randomly selecting a yellow marble from a bag of multi-colored marbles. Let's practice together.
