You will calculate the probability of simple and compound events using coins, dice, cards, and other everyday objects, and understand the difference between experimental and theoretical probability.
Exercises#
- Exercise 14.1 — Classical probability with equally likely outcomes (25 questions)
What you will learn#
- Theoretical probability of an event with equally likely outcomes.
- Sure, impossible and complementary events.
- Problems with coins, dice, playing cards, balls in a bag and spinners.
Key formulas and results#
- $P(E) = \dfrac{\text{number of outcomes favourable to } E}{\text{total number of possible outcomes}}$.
- $P(E) + P(\text{not } E) = 1$, and $0 \le P(E) \le 1$.
