There are five marbles in a jar. Three marbles are black and two are teal. You choose one marble without looking. Based on this infomation answer the following questions. The first marble you choose is black. You did not put it back in the jar. You choose another marble without looking. What is the probability that the second marble you choose will also be black?
Re: There are five marbles in a jar. Three marbles are...
The probabilty would be 50%.. (There are 2 black marbles out of a total of 4 marbles in the jar and so the chances of the second marble also being black is 2/4)

The polish can perform wonders and boost the look of marbled floors. Because it is extremely porous, these people get scratched very easily by white vinegar, fruit, tomato juice or some kind of other activities which contain acids. As well as certain kinds of marble that will get etched by drinking water.
Therefore marble polishing should be completed with the best materials.
If you have nine marbles in a bag, four of which are blue, then the probability of reaching in and pulling out a blue marble is four out of nine, or 4 divided by 9. Stay in the normal computational mode and press 4 / 9 = If you want to know the probability of pulling out three (for example) marbles and getting at least one blue marble, then you get into combinatorics. The answer depends on whether or not you replace each marble after pulling it out (Sampling with/without replacement). Probability is a rich and varied field of mathematics. People have spent lifetimes studying it.
Since there are 3 blue marbles and 7 non-blue marbles for a total of 10 marbles, the probability of choosing a non-blue marble is 7 out of 10. The probability of choosing another non-blue marble depends on whether you put the first marble back or not. The steps for solving a probability problem depends on the problem. It's like asking "What are the steps in getting to grandmother's house?" You might be able to get in your car, drive for an hour, and get there. Or you might take a bus or train. In my case, I'd have to go to an airport and board a flight (or else get to a port and board a ship). There's no way I can get there by road.
Thank you for your question. It appears you are playing a modified version of Aggravation. The original rules from Hasbro call for the use of one die. The player must move only one marble the full amount on the die. If the player can not move the full amount of the die, his/her turn is over.
Other keys to moving your marble according the the original directions are:
You can only move a marble out of the "base" and onto the "start" space with the roll of a 1 or 6.
You get an extra turn when you roll a 6.
You can jump over or land on an opponents marble (aggravate it) but can't jump over or on your own marble.
A "aggravated" marble (one that has been landed on) is to be placed back in the "base" area to be started over.
You can use the "star" and "center" spaces for shortcuts. However, the center space must be landed on and the roll of a 1 is the only way off the center space.
You must move all 4 marbles into the "home" area by the full roll of the die to complete the game.
Here is a link to the directions: http://www.hasbro.com/common/instruct/Aggravation_(2002).pdf. My personal opinion on your situation with the 3 and 4 dice rolls is that he could chose which marble to move 3 and which to move 4. But, the full use of the amounts of the dice must be used and the total on one die can not be split by two different marbles (a 4 die can't be split into a 2 and a 2).
Hope this helps and doesn't "Aggravate" you more! :0) Have fun playing!
I clean my marble with a mild dish soap. Dry. Then spray the ball with Pledge or some other furniture polish. Let dry for a few minutes and then polish with a lint free cloth. I have to do mine every 6 months or so. When cleaning the contacts I only use a small paintbrush. If you get alcohol on the sensory window, although using a q-tip, you can still scratch the surface.
