Sandra has a bag containing three coloured counters: red, blue and green.Draw a tree diagram to show the possible outcomes when one Counter is drawn from the bag at random, then returned to the bag before another counter is drawn at random.

Four cards marked A, B, C and D are in a container. A card is drawn, the letter noted, and then it is replaced. Another card is then drawn and the letter noted to make a two-letter combination. Draw a tree diagram to show the sample space in this experiment.
