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.

What is the probability of choosing a marble that is not blue in problem 2?
if there is a jar containing 5 red marbles 6green and 4 blue what is the probability off not chossing a blue marble
What is the probability of choosing a marble that is not blue if a jar contains 4 red 7 green and 5 blue marbles?
5:16
What is the probability of choosing a green marble from a jar containing 4 red 7green and 5 blue marbles?
7/(4+7+5) = 7/16 = 43.75%
What is the probability of getting a red marble out of a bag of twenty?
4 If the marbles are all red - 100%. You need to give the number of each different colored marble
If you have a bag containing 24 marbles If the probability of drawing a red marble is twice as likely not drawing a red marble how many red marbles are in the bag?
Suppose probability of drawing a red marble is p. Then p = 2*(1 - p) that is p = 2 - 2p or p = 2/3 So 2/3 of the 24 marbles are red 24*(2/3) = 16 red marbles.
