We moved on to Probability this Sunday.
We talked about experimental probability where we use the number of times an event happens to compare with total number of trials.
We talked about theoretical probability where we compare number of ways an event can happen to the total number of equally likely outcomes. The key word here is “equally likely”.
Important fact: P(an event happens) + P (the event not happening) = 1
We then talked about “Odds”, odds for winning is defined as the probability of winning over the probability of not winning, while odds against winning is defined as the probabilty of not winning over the probability of winning.
Odds can be bigger than 1, while probabilities cannot be over 1. We can easily convert from odds to probability.
Homework is the following:
