📌 Understanding Probability Calculation

Probability is a measure of the likelihood that an event will occur. The formula is:

  • P(E) = (Number of Successful Outcomes) / (Total Possible Outcomes)
  • Probability values range from 0 (impossible event) to 1 (certain event).

📌 Example Calculations

🔧 Practical Applications of Probability

1. Statistics & Data Science: Used to analyze and predict outcomes.

2. Gambling & Gaming: Determines winning chances in games of chance.

3. Risk Assessment: Helps in making decisions based on likelihoods.

❓ FAQs

Q1: How do I calculate probability?
✅ Use the formula P(E) = Successes / Total Outcomes

Q2: What does a probability of 0 mean?
✅ It means the event is impossible.

Q3: What does a probability of 1 mean?
✅ It means the event is certain.

Q4: Can probability be greater than 1?
✅ No, probability values always range between 0 and 1.

Q5: Why is probability important?
✅ It helps in **predicting future outcomes and making informed decisions**.
