Probability and Outcomes in Experiments

The video tutorial by Mr. Wooley covers calculating probabilities for chance experiments with equally likely outcomes. It explains how to estimate probabilities by dividing the number of observed occurrences by the total number of observations. The tutorial includes examples such as drawing colored cubes, flipping coins, rolling dice, and selecting letters. It compares theoretical and experimental probabilities and discusses sample spaces. The video concludes with applying probability concepts in games involving spinners.
