# Finding Probability

There are two basic parts of probability. There is a total number of possible outcomes, and there is number of favorable outcomes. The total number of possible outcomes, I like to think if the number of possible outcomes as however many there are in the running.

For example, the total number of possible outcomes would be 8, and the number of favorable outcomes for me to grab a blue tile would be 3/7.

Now, try and find the probability of the spinner landing on a green tile.

This is the last one. What is the probability of pulling out a blue marble?
