AIM: How can we determine the probability of an event?
HW: Unit 5 "What Do You Expect?" - ACE #1-5, 19; p.17, 20
The weather forecaster says the chance of rain tomorrow is 10%. What does this mean? Should you wear a raincoat?
The concept of probability was introduced in class today. We discussed that probability is "the likeliness of an event occurring" and that it is always a number between 0 and 1. Probabilities can be expressed as percents, decimals, or fractions. We looked at a situation with Kalvin and his mother using the flipping of a coin to determine which cereal he should eat in the morning, "Cocoa Blast" or Health Nut Flakes." Students intuitively were able to make judgements on probability. We also briefly discussed the two main types of probability - theoretical and experimental.
Students used number cubes to more closely investigate theoretical and experimental probability.
