A box contains the following items; 16 balls 21 cubes 5 pyramids 11 cylinders Two items are to be chosen at random in sequence. Evaluate the following probabilities assuming first that the first shape is replaced before the second selection and secondly that the first shape is not replaced before the second selection is made this will mean you have two answers for each part) Explain what replacing (or not replacing) between selections means for the events in this experiment. (Correct terminology please!) a) What is the probability of selecting a ball followed by a cube b) What is the probability of selecting a ball and a cube Explain whether and why questions a and b are different Use the multiplication rule to calculate the probability of selecting two pyramids
