Worked Example Your Turn There are 4 yellow and 5 red balls in a bag. A ball is picked and not replaced. A second ball is then picked. Complete the tree diagram showing the probabilities on each branch. There are 3 yellow and 5 red balls in a bag. A ball is picked and not replaced. A second ball is then picked. Complete the tree diagram showing the probabilities on each branch. @mrbartonmaths
The numbers of coloured balls in a bag and the number of picks are given in each question. Each time a ball is picked, it is not replaced.
