Understanding independent and dependent events in probability is a lot easier when you look at some simple examples.
Independent Events:
Coin Tossing: When you toss a coin, the result of the first toss (heads or tails) doesn’t change the result of the second toss. So, if you toss a coin twice, what you get the first time does not affect the second time. They are independent!
Rolling Dice: If you roll a die, the result of that roll (a number between 1 and 6) doesn’t change what happens on the next roll. Each roll stands on its own and is independent.
Dependent Events:
Drawing Cards: Think about a regular deck of cards. If you draw one card and don’t put it back, the next draw is affected by the first one. For example, if you draw an Ace first, there are fewer Aces left for the next draw. This makes these events dependent.
Picking Marbles: Imagine you have a bag filled with different colored marbles. If you take one out, you change how many are left in the bag. This affects the chances of what you might draw next, making these events dependent too.
These examples should make it clearer how independent and dependent events work in probability!
