Two bags - 100 bags - The computation of probability is the same process - you take the number of desired results and divide by the number of possible results. The difference here is that the desired result sets do not intersect the possible result sets for the two bags, but the computation is the same - desired divided by possible.
There would be a 7/19 or 36.84% chance of drawing a blue marble from the bag.

The answer depends on how many cards are picked, whether they are picked at random, from what sort of pack, and whether or not cards are replaced before the next one is picked. The probability that a single card, picked at random from a regular 52 card deck is red, is 0.5
If the winning numbers are picked at random, the probability is 1 in 169911.

The odds are set so that the longer you play, the more probable it is you will lose. Its like betting on a jar with a thousand marbles in it. 600 of the marbles are black and 400 are white. You bet $1 each time a marble is picked and your bet is that a white marble will be picked. If a white marble is picked, you get your $1 back plus an additional $1. As the marbles are being picked, you may be winning at times but ultimately you will lose $200 because there are 200 more black marbles than white marbles. This may seem very simplistic but it is exactly what happens when you play craps.
What is the probability that the letter P is picked when a letter is picked at random from the word STUPID!
Well, honey, if you're reaching into that bag three times and each time you're pulling out a yellow marble and then putting it back in, the probability of picking a yellow marble each time is 8/21. Multiply that by itself three times because you're picking three marbles, and you get a probability of 512/9261. So, good luck with those yellow marbles, darlin'!
If a student is picked at random what is the probability that he/she received an A on his/her fina?
If only one person is picked at random then the probability is 1/16 = 0.0625
If you pick only one marble from the bag, at random, it can be any one of 26 marbles. Out of these, 5 of the marbles are green. Thus, there are 26 possible outcomes out of which 5 are favourable - to the event that the marble is green. Therefore the probability of a green marble is 5/26. The calculations become more complicated if you consider choosing a green marble in several attempt: it depends on whether or not the marbles are replaced before the next one is picked.

The probability that a date picked at random is February 30th is zero, as there is no February 30th, even in leap years.

Pr(Both picked 3) = 1/16Pr(Both picked the same) = 1/4.
Assuming then that there are 100 numbers, 1-100, the probability of the number 23 being randomly picked out of 100 is: 1/100 or 0.01.
