The Formula of Frequency of Hope and the Opportunity of Complement A Genesis

The Formula of Frequency of Hope and the Opportunity of Complement an Event - Reunite with The Basic Mathematical Formula The material we will discuss together this time is still about opportunity. After this we learn about Understanding the Range of Opportunity Values ​​ This time we will try to understand the frequency of hope and the chance of the complement of an incident complete with the discussion of understanding, the formulas used and examples of problems and ways Finish it. Immediately we see the topic of discussion below:

Definition and Formula Frequency of Hope

What is meant by the frequency of expectation is the result of Multiplication between the probability of occurrence of an event multiplied by the number of experiments performed. As a conoth, on a coin toss, the probability value of the image is 1/2. If the toss of the coin is done 30 times then the expectation of the image is:

1/2 x 30 = 15 times

Since it is referred to as hope, it is only natural that from 30 throws that can occur the appearance of the image as much as 14 times and the appearance of the number as much as 16 times. The number of events that can be expected from an experiment is called the frequency of hope. The usual formulas used to find the expected frequencies are:

Frequency of expectation of occurrence A = P (A) x number of experiments

To understand how to use the above formula, consider the following example:

:
A dice thrown in 80 times. Calculate the expected frequency of the appearance of the dice less than 4!

Solution:
Suppose A = occurrence The emergence of the dice less than 4,
then A = 1, 2, 3 and P (A) = 3/6 = 1/2

Frequency of expectation = P (A) x number of experiments
Frequency of expectation = 1/2 x 80 = 40


The dice less than 4 is 40 times.
Complementary Opportunity An Event
What is meant by the complementary probability of an event is the probability of an event contrary to an event there is. The complement of occurrence A is the set of all incidents that are not A. The complement of event A can be written as A c . You need to remember that the chances of an event and its complement always amount to 1 means an event must happen or it will not happen. So the formula is:

P (A) + P (A c ) = 1
[194590]

P (A c Example:
When we throw a 6-edged die, the odds of not getting the side of the dice 4 are: [1945909]
P (4 c ) = 1 - P (4)
P (4 c ]
P (4 c ) = 5/6 ]
Probably quite a few brief comments on Frequency of Hope and Opportunity of Complement an Event Do you guys Can understand the above explanation well? Hopefully you can understand the explanation given above. Check out also other topics about the material opportunities that have been discussed in this blog. Happy learning and see you in other articles.

Units of Size The number of Lusin, Gross, Rim, and Kodi

Unit Size The Number of Lusin, Gross, Rim, And Kodi - When carrying out your daily activities you must have heard some terms like Lusin, Gross, Rim, and Kodi in mathematics the term is called a unit of measure of quantity or quantity. This unit is commonly used to express the number of items or objects. For those of you who do not know or have not memorized by the size of the unit, let us study it together by listening to the discussion The Basic Mathematical Formula on the following unit size sums: The most commonly used unit of measure quantities is : 1 dozen = 12 pieces 1 gross = 144 pieces = 12 Lusin 1 score = 20 pieces ] 1 rim = 500 glue Bar The use of units of measure of the number of Lusin, Gross, Rim, and Kodi The above sizes are usually used in accordance with certain types of goods, for example: Lusin The term dozen is more often used to express the number of items such as glasses, plates, spoons, jars, and so on.

Example Problem Arithmetic Social About Discount / Rebate

Example Problem Arithmetic Social About Discount / Rebate - the meaning of rebates are rebates granted to a product or service. We are more familiar with rebates as a discount. You'll often see at the supermarket or supermarket there are a lot of rebates or discounts, it is an example of a rebate. If you are curious about how to calculate the price cuts, the Mathematical Formulas Basic will give his review to you through examples to the following: Example Problem Discussion and Arithmetic Social About Rabat Example Problem 1 Melly want to buy a dress for Rp 120,000. It turned out that the clothes receive a rebate of 20%. What is the size of the rebate? Answer: clothes Price: Rp 120,000 Rabat: 20% x 120,000 = 20/100 x 120,000 = 24,000 Thus, rabatnya amounted Rp.24.000 Example Problem 2 [1945901million] A Shop, gives a 5% discount for every purchase math book.
