From the table, we can see that that there are 36 sums. Remember if one 1 is rolled all ‘S’ points will be lost. If the sums are 2, 3, 4, 10, 11, 12, then the player wins. We can see this if we enumerate all the possible sums in a table. In this post, we are going to design a game that will demonstrate the power of probability. The famous correspondence between Fermat and Pascal in 1654 was one of the earliest accounts on how to use mathematics formally in order to solve a fair game of chance. One of the origins of of probability as a field in mathematics was solving games of chance. From this calculation, the casino has actually two wins for every three games played. We can also see that although the sum contains numbers which are the same, they are all results of 2 distinct pair of dice. a game where the outcome is strongly influenced by a random number generator in which contestants may choose to bet money on the outcome The students would record an 11 under the ‘S’ and then make a decision. So, let’s say the game has just started and the teacher rolls a 6 and a 5. As mentioned above, the lowest sum is 2 and the largest sum is 12. Looking at the game above, it seems that the game favors the player. Below are the instructions on how to play the game. From the table above, if we count the sums 2, 3, 4, there are only six of them. If the sums are 5, 6, 7, 8, 9, then the casino wins. In reality, the casino will actually win using the game designed above if numerous games will be played. Despite the dice is fair (unloaded), as the number of games increases, the casino will eventually actually win. This means that the probability of the player winning is while the probability of the casino winning is . On the other hand, there are only five possible sums that will make the casino win:  5, 6, 7, 8, and 9. Although most casino games actually obviously favor the casino, the game below is a bit more conservative (or should I say ‘deceptive.’). • Gain experience of designing and carrying out a probability experiment. We will use probability to create a game that looks like as if it favors the player, while in reality, it favors the casino. The dice to be used in the game below is the standard 6-sided die whose number of dots are from 1 to 6. We have seen above the power of probability on how to assure game results. As we can see, there are six possible sums that will make the player win: 2, 3, 4, 10, 11 and 12. School math, multimedia, and technology tutorials. This means that the smallest possible sum is 1 + 1 = 2 and the largest possible sum is 6 + 6 = 12.

However, since there are 36 possible sums, 36-12 = 24 sums will make the casino win. For example, although there are six 7’s (green cells), each of them are results of distinct addends. The famous correspondence between Fermat and Pascal in 1654 was one of the earliest accounts on how to use mathematics formally in order to solve a fair game of chance. For instance, the sum 6 + 1 is different from the sum 6 + 1 . If a player who has no mathematical background will be given a chance to choose between the two sets of numbers above, they will probably choose the one with the six possible sums. One of the origins of of probability as a field in mathematics was solving games of chance. Suppose the color of the two dice are red and blue, then we can create a table that will display all the possible sums as shown below. This is also the same with 10, 11, and 12. Therefore, there are only 12 possible sums that will make the player win. Do they remain standing for a second roll and take the chance that one or two 1’s are rolled?
