The tree diagram relates the weather forecast and school closings. Find the probability (as a percent) that the school is closed tomorrow if there is a
80
80% chance for heavy snow.
According to the tree diagram:
- There is an 80% chance of heavy snow, which will result in a school closure 100% of the time.
- There is a 20% chance of no heavy snow, which will result in a school closure 10% of the time.
Therefore, the probability that the school will be closed tomorrow is 80% (80% x 100%) if there is an 80% chance for heavy snow.
