When Year 9 students learn about probability, they often misunderstand a few key ideas. Here are some misconceptions to watch out for:
Gambler's Fallacy: This is when people think that past events can change future chances.
For example, if a coin has landed on heads five times in a row, some students might believe that tails is "due" to happen next.
But the truth is, every time you flip the coin, it’s always a 50% chance for heads or tails, no matter what happened before.
Confusion with Odds: It's important to know that odds and probability are not the same thing.
If the odds of an event happening are 3 to 1, you can find the probability by using this simple formula:
Probability (P) = Odds of the event / Total odds
Misinterpreting Randomness: Sometimes people think that random sequences should look random.
For example, a sequence like HHTHTHT might look like it has a pattern, but it's still random.
Understanding these ideas will give you a better grasp of probability!
