The probability of picking the #1 marble on the first draw is 1/12.
If you've done that, then the probability of picking the #2 marble on the second draw is 1/11.
If you've done that, then, the probability of picking the #3 marble on the third draw is 1/10.
If you've done that, then, the probability of picking the #4 marble on the fourth draw is 1/11.
etc.
etc.
So the probability of doing all of them in sequence is (1/12) x (1/11) x . . . x (1/1).
That's exactly the reciprocal of (12!). According to my $1.49 calculator, your chances
of success without peeking amount to about
0.00000020877 percent (rounded)
Not a smart bet.

What is get the marbles out of your mouth?
Stop mumbling.....I think it comes from the practice of old; In order to help overcome a speech impediment or just to have better elocution and pronunciation one would learn to speak while holding a small number of marbles in ones mouth. in time it becomes easier and easier to speak despite the mouthful, and the end result is once the marbles are removed you speak more clearly and understandably
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.
How do you use a z table?
A z table is used to calculate the probability of choosing something that is normally distributed. In order to use it, first a z score is needed. A z score is the number of standard distributions a value is away from the mean of the data. In order to find the z score, take the value of the datum, subtract the mean, then divide by the standard deviation. The result is a z score. Look up the z score on the table to find the probability of getting anything equal to or lesser than the value you chose.
What are the odds in favor of getting at least one head in 3 consecutive flips of a coin?
>>> 1:7 (or, if you like probability, 87.5%)I disagree. There are four possible combinations of three tosses (where order does not matter):HHHHHTHTTTTTThree of these combinations will show at least one head - only by throwing three tails will you not throw at least one head.Thus, the probability of throwing at least one head in three flips is 75%.
What are the chances you are going to toss 2 pennies 20 times How many times do you expect the 2 pennies will come up 1 head and 1 tail?
The key to probability is to identify how many outcomes are possible. Put a bunch of pennies on the table and have your son move them around to indicate how many possibilities there are for arranging two coins. He will quickly find that he can have HH, TT, HT, or TH So tossing two pennies will work out in one of these arrangements -- no matter how many times they're tossed. Probability is a fraction: the number of outcomes that match the criteria [I call these 'winners'] over all possible outcomes. Each of the outcomes in the list, then, has a 1/4 chance of happening. However, 2 of the outcomes result in one head and one tail [the order doesn't matter], so we can group thise to give the 1head-1tail choice a total probability of 1/2 Once you have the basic fraction of probability, he can multiply that by the number of tosses to work out the specific answers for your questions above

A bag contains 6 purple marbles and 7 white marbles Two marbles are drawn at random One marble is drawn and not replaced Then a second marble is drawn What is the probability that the first marble?
There are 13 marbles in total. The order is specified.P(1st is white and the 2ndis purple) = (7/13)(6/12) = (7/13)(1/2) = 7/26.

How can 4 red marbles make up one third of marbles and 3 blue marbles make up one fourth of the same group?
In order for 4 red marbles to be one-third of a group and 3 blue marbles to make up one-fourth of the same group the number has to equal 12.
What is the difference between 278 marbles and 46 marbles?
In mathematics, the word difference means the answer to a subtraction problem. In order to find the difference, 46 must be subtracted, or taken away from 278. This leaves 232 marbles.
Do you divide to find the probability?
Yes, you divide the number of expected outcomes by the number of possible outcomes in order to determine probability.
What is the probability of drawing a jack and a king?
The probability of drawing a jack and a king in that order from a standard deck is: P(J,K) = (4/52)∙(4/51) = 0.006033... ~ 0.006 ~ 0.6% The probability of drawing a jack and a king in any order is twice the above: P((J,K) or (K,J)) = 0.0112066... ~ 0.011 ~ 1.1%
What is the probability that you roll a six and one and three?
If the order of the numbers matters, then:The probability of a 6 on the first roll is 1/6.The probability of a 1 on the second roll is 1/6.The probability of a 3 on the third roll is 1/6.The probability of all three is (1/6 x 1/6 x 1/6) = 1/216 = 0.00463 = 0.463 % (rounded)If you're not concerned about the order of the rolls, only the probability of getting all three numbers, then:The probability of getting any one of them on the first roll is 3/6, or 1/2.The probability of getting one of the other two on the second roll is 2/6, or 1/3.The probability of getting the final one on the third roll is 1/6.The chance of all three without order then is (1/2 x 1/3 x 1/6) = 1/36 or 2.778% (rounded)
What is the probability of drawing 2 hearts and then a spade in that order from a deck of 52 cards?
In order to determine the probability of drawing 2 hearts and then a spade, in that order, from a deck of 52 cards, start by considering the first card. The probability of drawing a heart is 1 in 4. Since you have now reduced the number of hearts and the number of cards in the deck by one, the probability of drawing another heart is 4 in 17. Since you have further reduced the number of cards by one, the probability of drawing a spade is 13 in 50. Multiply these probabilities together, (1/4) (4/17) (13/50), and you get about 0.0153, or about 153 in 10000.
