Test Your Knowledge: Probability Questions with Real-Life Examples for Grade 6

📚 Quick Study Guide

• 🎲 Probability Definition: Probability is the measure of how likely an event is to occur. It's expressed as a number between 0 and 1, where 0 means the event is impossible, and 1 means the event is certain.
• 🔢 Formula: Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$
• 📊 Expressing Probability: Probability can be expressed as a fraction, a decimal, or a percentage. For example, a probability of $\frac{1}{2}$ is the same as 0.5 or 50%.
• 📅 Real-Life Examples: Think about flipping a coin, rolling a dice, or picking a card from a deck. These are all examples where you can calculate probability.
• 💡 Key Terms:
  • Event: A specific outcome or set of outcomes.
  • Outcome: A possible result of an experiment.
  • Sample Space: The set of all possible outcomes.
