5. Which of the following is a key point about Probability for Beginners?

   1. An event's probability is a number between 0 (impossible) and 1 (certain)
   2. Probabilities over all outcomes sum to 1
   3. Expectation: the average outcome you would get over many repetitions

6. What is one important takeaway from studying Probability for Beginners?

   1. Independent OR: approximately add them if small
   2. Independent AND: multiply probabilities (P(A) × P(B))
   3. Dependent: use conditional probability (next lesson)

7. What is the key insight about "Coin toss example" in the context of Probability for Beginners?

   1. safety eval
   2. worst-case
   3. P(heads) = 0.5. P(tails) = 0.5. They sum to 1. Over 1000 tosses, you expect roughly 500 heads — not exactly, but close.
