4. We have a supply of flowers of 3 different colours: red, white and yellow. How many ways are there to choose 4 flowers, provided we choose at least 1 flower of each colour? With the problem as above but we drop the requirement that at least one flower of each colour is to be chosen, what will be the number of ways?
