Mike has 4 blue balls, 6 green balls and 10 yellow balls what is the probability that he will pick a yellow ball.
It would be worked out by adding 4+6+10 to get 20 and then it would be number of yellow balls over total number of balls which would be 10/20. Depending on ability this may then be simplified down to 1/2.
