1. Probability “The Study of Chance.”

2. Probability P(Red ball) = 4 out of 7 = 4/7

3. Wwhat we’re going to cover : rreminder of basic definition of probability, including the best way to write a probability. Wwhat is the difference between experimental and theoretical probability Hhow to deal with combined events by using a probability diagram and a tree diagram. (e.g. what is the probability of rolling a 6 and then a 5?) Hhow to calculate the probability of a combined event by considering all the outcomes. Probability

4. Fractions – adding subtracting and multiplying Changing from fractions to decimals and possibly to percentages GradeWhat you need to do… BCalculate combined probabilities using and / or rules. C Use relative frequency as an estimate for probability, calculate the probability of combined events. What is the p(event not happening)? DUse the probability scale 0 to 1, experimental probability can give you different results. Probability – links / grades
