A bag that has 7 greens marbles 3 blue marbles and 12 white marbles what is the probability of selecting a white marble on each of the three tries if the marble is placed back after each pick?
12 white marbles from (7+3+12) = 22 marblesChance of a white marble on first pick = 12/22 = 6/11.Chance of a white marble on second and third picks are the same, as the marble is replaced.So, the chance of a white marble three times is 6/11 * 6/11 * 6/11 = 216/1331 = approximately 16.23%
What can you do with marbles?
A:This doesn't seem like a math question. The obvious answer is to play the game of marbles with them. When I was a boy, this was a popular game for kids. The idea is that one marble is designated as the shooter . The other marbles are placed in a ring drawn in the dirt.You place the shooter in one hand and using your thumb, shoot it at one of the marbles in the ring , trying to knock it out of the ring. if you succeed, you get a point and another shot. If you " play for keeps" each players puts a certain number of his marbles in the ring and you get to keep the marbles you knock out.There is common board game called Chinese checkers that uses marbles for men. The board has holes in it to hold the marbles.A:As far as marbles and math go, a bag containing various colored marbles is often used to demonstrate probable outcomes. For example, if a bag contains 3 blue marbles, 3 red marbles, and 1 yellow marble, what is the probability that the first two marbles pulled will be of different colors?(In this example, the odds are 5 out of 7, or about 71%. If either a red or blue marble is pulled first, which will each happen 3/7 of the time, there would be four out of six marbles left whose color doesn't match. If the yellow marble is pulled, which will happen 1/7 of the time, the next marble is guaranteed to not match.)

What is the probability of five books being placed in alphabetical order of their titles if randomly put on a book shelf?
There are 5! (that is, 120) distinct ways to arrange five items. Only 1 of them will have the books in alphabetical order by title. So the probability that it happens by random is 1/120.

The first letter of each month is written on a card and the cards are placed in a bag. What isthe probability of pulling out a J, placing it back in the bag, and then drawing an M?
So, to start with, the probability of drawing a J is 3/12 since there is January, July, and June. So there's a 25% chance of getting J first. There are 2 months starting with M, March and May, so by itself there is a 2/12 chance of that happening, or a roughly 17% chance. However, since we only care about drawing an M after drawing a J, we have a 3/12 chance of the first draw, and the other 9/12 possibilities we don't care about because they've already failed. So out of the 3/12 times where we draw a J, we then have a 2/12 chance of drawing an M. So 3/12 * 2/12 = 6/144, about a 4% chance of drawing these letters in this order. Specifically, 0.04166666
