  2. What is Probability? It’s the branch of mathematics that deals with calculating the likelihood of a given event's occurrence

  3. How is probability expressed? • It is expressed as a number between 1 and 0 • It is usually expressed in fraction representation • An event with a probability of 1 can be considered a certainty • for example, the probability of a coin toss resulting in either "heads" or "tails" is 1, because there are no other options, assuming the coin lands flat. • An event with a probability of 0 can be considered an impossibility • for example, the probability that the coin will land (flat) without either side facing up is 0, because either "heads" or "tails" must be facing up.

  4. How to calculate probability number of ways that outcome can happen = Probability of an outcome total number of possible outcomes

  5. Calculating Probability in Action… A bag contains 12 blue buttons, 10 red buttons, 3 yellow buttons and 7 green buttons. If a button is picked at random what is the probability of it being: • Blue? • Red? • Yellow? • Green?

  6. Probability of Blue… 12 blue buttons 10 red buttons 7 green buttons + 3 yellow buttons 32 Total buttons 12 blue buttons 32 total buttons 12 32 3 8 Probability = = =

  7. Probability of Red… 12 blue buttons 10 red buttons 7 green buttons + 3 yellow buttons 32 Total buttons 10 red buttons 32 total buttons 10 32 5 16 Probability = = =

  8. Probability of Yellow… 12 blue buttons 10 red buttons 7 green buttons + 3 yellow buttons 32 Total buttons 3 yellow buttons 32 total buttons 3 32 Probability = =

  9. Probability of Green… 12 blue buttons 10 red buttons 7 green buttons + 3 yellow buttons 32 Total buttons 7 green buttons 32 total buttons 7 32 Probability = =

  10. TEKS • (6.3)  Patterns, relationships, and algebraic thinking. The student solves problems involving direct proportional relationships. The student is expected to: (A)  use ratios to describe proportional situations; (B)  represent ratios and percents with concrete models, fractions, and decimals; and (C)  use ratios to make predictions in proportional situations.
