I have 6 red balls and 4 blue balls in a bag. I withdraw a ball from the bag, note the colour and do not replace it. I then withdraw a second ball from the bag and note the colour.
What is the probability of withdrawing a red ball and a blue ball in any order?
Give your answer correct to 3 decimal places.
You could use a probability tree to help you with your calculations though you do not have to show it.
