Rework problem 17 from the Chapter 1 review exercises in your text, involving drawing balls from a box. Assume that the box contains 7 balls: 2 green, 3 white, and 2 blue. Balls are drawn in succession without replacement, and their colors are noted until a green ball is drawn or two white balls are drawn.

How many outcomes are there in the sample space?

Please explain the steps if possible, so i can understand how its done :)
