Probability of Simple Events

How the lesson starts: Probability of Simple Events

Ollie's game booth
Welcome to the beach fair! Ollie the octopus runs a game booth with dice and bags of counters. Ollie asks, how likely is it that you roll a 4? Let's learn how to measure luck!
Likely words
Ollie has five bags of blue and red counters. Draw one without looking. 0 blue: blue is impossible. 1 blue, 8 red: unlikely. 4 blue, 4 red: equally likely. 8 blue, 1 red: likely. All blue: certain!
Roll a 4
A fair die has 6 faces, and each one is equally likely. How many faces show a 4? Just 1. Probability is the ways to win over all the outcomes. So P of rolling a 4 = 1/6.
