When trying to find the probability of drawing a violet marble from a jar containing 9 red, 4 brown, 10 yellow, and 8 violet marbles, how many desired outcomes are there?

When trying to find the probability of drawing a violet marble from a jar containing 9 red, 4 brown, 10 yellow, and 8 violet marbles, how many desired outcomes are there?  Solution: We need to find the probability  of drawing a voilet marble when there are 8 voilet marbles. Drawing any of thr voilet marble will be a favourable or desired outcome.  As, there are 8 violet marbles and getting any of the voilet marble is a desired outcome . So, the desired outcomes are 8.  Probability  is desired outcome /total outcome. There are 8 voilet marbles and  there are 31 marvels. So probability of getting a voilet marble=8/31  desired oucomes=8

could you reply to this with the question so i can ?

the answer is simply just 6n add the two together as they have an n
