A box contains 1 green, 2 yellow, and 3 red marbles. Two marbles are drawn at random without replacement. What are the odds of each event occurring?
1. Drawing to different colours?
I do not deal with odds.
But I can give the probabilities. .
To have two different colours, it must be one of those three.
As my answer I got 11/4 I added up all the success probabilities subtracted by one to get the failures and then I did probability of success/ probability of failure.
