Activity Notes We have 2 balls - 1 Red and 1 Green. We mix and drop them into a vertical box. What color ball drops first? The following
Guided Activity Do the experiment 200-1000 times. - What is the percent of green first?
- What is the percent of red first?
Now for some dreaded theory ... - Theoretically, how often should the green ball drop first into the box?
- Theoretically, what is the probability that the red ball will drop first?
- Does this agree with your experimental results?
- What other real life situations give this kind of probability?
"Mutually exclusive" means both events cannot happen at same time and "complete" means no other event can occur. |
