Number of different possible choices = 8 + 6 + 9 = 23
Number of available successful choices (blue marbles) = 6
Probability of success = 6/23 = 0.26087 = 26.087 %(rounded)

What is the probability for choosing a red marble?
More information is required. Probability by definition is the proportion of a part, called a sample, to the whole, called a population. Thus in this question, we are given the sample only and without the population, it is impossible to calculate the probability. We need to know the size of the population. As a guide, supposing there are 8 red marbles in a jar containing 40 marbles, then the probability of choosing red is 8/40 or 1: 0.2. There is 20 per cent probability of choosing red.

A bag contains 6 red marbles 4 blue marbles and 1 green marble What is the probability of choosing a marble that is not blue?
We will assume that the bag contains 11 marbles (this is not a trick question!), so 4 are blue and 7 are not blue, so the probability of a color other than blue is 7/11.

one out of nine
When a jar contains 5 white marbles 3 blue marbles and 2 green marbles and if one marble is drawn at random then what is the probability that it will be blue?
There is a probability of 3 that it will be blue.
A bag contains 11 blue marbles 10 purple marbles 17 red marbles 15 green marbles and 3 yellow marbles What is the probability of pulling out a blue or a red marble?
There are 11+10+17+15+3=56 marbles in total. Of those marbles, 11 are blue and 17 are red, so there are 11+17=28 blue and red marbles. Therefore the probability of choosing a blue or red marble is 28/56=.5, or 50%.
