Statistics And Probability








                    Example:
                    A coin and  a pentagonal spinner with sectors 1,2,3,4 and 5 are rolled  and spun resp€ctively-
                    a) Draw a grid to illustrate  the sample  space ofpossible outcomes-
                    b) How many outcomes are possible?
                    c) Use your grid to determine the probability of getting:
                        i) a tail and a 3
                        ii) an odd number
                       iii) a head and an even number
                        iv) a head or a 5






















                    Trec diagr:rnr

                    - A tree diagram  is a mcans which can be used to find the number of possible
                    outcomes of experiments where each experiment  occurs  in a finite  number ofways-
                  Example:
                  Two dice are tossed-Find the set ofpossible  outcomes.
