There are 1 red, 5 green and 4 blue counters in the pot.[Notes for Teacher: The film will go on for ever! It shows a red, green or blue counter being taken from at random but in proportion to the number of red, green and blue counters in the pot. Students might make a tally chart to see the relative numbers of counters being pulled out of the pot then divide 10 in the same ratio.]
