Probability Fundamentals

• Mutually Exclusive Events: If A and B are mutually exclusive, then P(A ∪ B) ≠ 0.
• Independent Events: Events are independent if their probabilities match, such as P(A) = P(B) or P(A|B) = P(A).
• Conditional Probability Example: Find P(driver is age 65+ | driver is female) = P(driver is female and 65+) / P(driver is female).
• Key Formulas:
  • P(S ∩ Y) = P(S ∩ Y) / Total
  • P(S|Y) = P(S ∩ Y) / P(Y)
  • P(Y ∪ S) = P(Y) + P(S) - P(Y ∩ S)

It's recommended for teenagers to focus on friendships rather than romantic relationships. It makes total sense; the majority of teenagers are not ready to handle a relationship. Teenagers are still young and still have a long way to go in their lives. You don't know when or where you'll meet your soulmate. The odds are enormous!
