Understanding and Formulas of Mathematical Opportunities - Have you ever played a ladder snake? In the game of the ladder you will certainly use the dice to determine the number of steps you should take. In the process of throwing dice, the result or number that may muncil is 1,2,3,4,5, or 6. Well the possibility of the emergence of numbers when rolling dice is one example of Mathematical Opportunities.

Another example of mathematical odds is the tossing of coins.the moment of throwing a coin there are two possible sides that appear. The first is the number (A) and the second side is the image (A) .Now, in the material this time, the basic mathematical formula will provide a material summary of the notion and the probability formula in mathematics Let us refer to the summary of the material as follows:

Understanding the Definitions and Formulas of Opportunities in Mathematics [19459006 Definition of Opportunity

Opportunities can be defined as a (19459007)
[1945904]

In the matter of opportunity, there are known terms that are often used, Such as:

[1945909]

The Sample Room

Represents The set of all possible experimental results.

Sample Point

Is a member that exists in the sample space

Genesis [1945909]

Is a subset of the sample chamber.

FORMULA OF MATHEMATICS

Frequency is the ratio between the number of experiments performed by the number Events observed. The frequency can be determined by using the formula:

If each sample point of the sample space member S has equal probability, then the probability of event K whose member number is expressed in n (K) can be known by the formula:

The probability of occurrence of events can be estimated by the notation below:

If the value of P (K) = 0 then the incident K is impossible to happen

If the value of P (K) = 1 then the incident K (1945901)

Observe an example of the problem below:

Example Problem 1

In the process of throwing a dice, determine the odds of the emergence of the odd-numbered dice

[194590]

Answer:

The sample space S = 1,2,3,4,5,6

n (S) = 6

The odd dice = 1,3,5

n (S) = 3

Compound Genesis

Compound events are two or more events that Operated so that a new incident

An incident K and a complementary incident of K 'satisfies the equation:

P (K) + P (K ') = 1 or P (K') = ]
Example Problem 2

from a set of bridge cards, drawing one card at random. Determine the chances of taking a card that is not As.

Reply

The number of bridge cards = n (S) = 52

number of cards As = n (K) = 4

P (K) = 4/52 = 1/13

the odds are not taken as As = P (K ') = 1-P (K) = 1 -
