Day 70: Go Fish Binomials
Needed a catch for practicing binomial probabilities in AP Stats. This summer I saw these fishing rods for children aged 1-3…perfect for the high school!
So I put together 10 problems, cut them apart, folded and put a paperclip on each one. That way the magnet on the “fishing rod” would pick up problems from the “pool.” Dorky, but the boys at least had some fun.
The problems were great and the kids were focused and building confidence in their ability to approach and do problems about probability. Here’s an example (with answers :)):
It has been determined that 5% of drivers checked at a road stop show traces of alcohol and 10% of drivers checked do not wear seat belts. In addition, it has been observed that the two infractions are independent from one another. If an officer stops five drivers at random:
a. Calculate the probability that at least one of the drivers checked has committed at least one of the two offenses. 0.5431
b. Calculate the probability that exactly three of the drivers have committed at least one of the two offenses. 0.3344
How do you create engaging practice opportunities?
