🎲 Probability of Independent Events
This quiz focuses on understanding theoretical and experimental probability, calculating the probability of independent events using the multiplication rule, and representing outcomes through tree diagrams and tables. You'll explore fair and unfair games, and apply compound probability concepts to real-world scenarios. **What you'll learn:** - How to calculate theoretical and experimental probability - Apply the multiplication rule for independent events - Interpret and create tree diagrams and outcome tables - Distinguish between fair and unfair games - Solve compound probability problems in practical contexts

- Question 1
You roll a fair six-sided die. What is the theoretical probability of rolling a number greater than 4?
- Question 2
A student spins a spinner 50 times. It lands on blue 18 times. Based on this experiment, what is the experimental probability of landing on blue?
- Question 3
If you flip a fair coin and roll a fair die, these two events are independent, meaning the outcome of the coin flip affects the outcome of the die roll.
- Question 4
You flip a fair coin twice. What is the probability of getting heads on both flips?
- Question 5
A tree diagram shows all possible outcomes when spinning a spinner with 3 sections and rolling a six-sided die. How many branches should appear at the final level of the tree?
- Question 6
A fair game is one where each player has an equal theoretical probability of winning.
- Question 7
You draw one card from a standard 52-card deck, replace it, shuffle, and then draw again. What is the probability of drawing two hearts?
- Question 8
A table shows the outcomes of rolling two dice. How many rows and columns should the table have to show all possible outcomes?
- Question 9
The probability of an impossible event is 1.
- Question 10
You spin a spinner with equal sections labeled A, B, C, and D, then flip a coin. What is the probability of spinning a B and flipping heads?
- Question 11
In a game, you win if you roll a 6 on a die. Your friend wins if you roll any other number. Is this a fair game?
- Question 12
You pick a marble from a bag without looking, replace it, and then pick again. The bag contains 3 red, 2 blue, and 5 green marbles. What is the probability of picking a red marble both times?
- Question 13
When calculating the probability of two independent events both happening, you add the individual probabilities together.
- Question 14

- Question 15
