3/6 or 1/2 or 50%
The probability of drawing a white marble is .46
The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.

select a marble from the jar, return it , and record times
25/50 gives the probability of selecting a blue marble
The probability of choosing a green marble from this jar would be 6/15. You get this answer by adding up the sum of all the marbles.
that it is a marble? 1. Unless I have lost my marbles.
The odds of pulling a red marble on the first try is 4/15 or about .27 and the probability of drawing a white marble the second time if a the first is a red marble is 5/14 or about .36. the odds of both happening is the product of the probabilities of the other events, or 2/21.
It is not. There are only two possible outcomes for each toss of a coin whereas the number of possible outcomes when selecting a marble from a bag will depend on the numbers of distinct marbles in each bag. The coin toss generates a binomial distribution the marbles experiment is multinomial.
