Calculate the percentage success rate and how to calculate the percentage achievement rate

The odds of success don't change!

1) If you succeed for the first time, the chance of success for the second time is still 89%.The third time it was 89%. It's 89% for the 10th time, and 89% for the nth time.

2) If you fail once, then the chances of success the second time or the third time are still. The tenth time, the nth time.

Therein lies mathematical expectations.

The problem assumes a mathematical expectation of e. Since the chance of success is 89%.

The nth experiment was successful.

then the first success p=89%.

The second success p=89%*89%=

3rd success p=

The nth success is p=

It is expected that e=1*approximately equals) more than four points (i.e., purely theoretically, the fourth time will succeed at the latest), so it seems that the probability of success is greater later. Not really. The odds are constant.

50% chance of failure, 50% chance of two consecutive failures 50% 50% = 25%, and two consecutive successes are also 50% 50% = 25%.

The chance of failing n times in a row is 50% to the nth power.

A percentage indicates how many percent of a number is another number, also called a percentage or percentage. Percentages are not usually written as fractions, but are represented by the symbol "%" percentile. Percentages tend to indicate a proportional relationship, but percentages can sometimes exceed 100%; And percentages have different meanings in different situations.

The formula for calculating the achievement rate should be: 2 - the number of completions and the number of plans.

1. Plan -500, completion -100, then the completion rate is 2-(-100) (500)=180%.

2. Plan -500, completion -400, then the completion rate is 2-(-400) (500)=120%.

3. Plan -500, complete 50, then the completion rate is 2-(50) (500)=210%.

4. Plan -500, complete 150, then the completion rate is 2-150 (-500) = 230%4. Plan -500, complete 400, then the completion rate is 2-400 (-500) = 280% Extended data completion rate: the percentage of tasks that have been completed in the total tasks. The positive completion rate is relatively easy to calculate, and it can be divided by the total number of completions; The completion rate of a negative number is calculated as the number of 2-complete plans.

How do I calculate the completion rate where the number of plans is negative and the actual number is positive?

Example: The number of plans is 1 million, and the number of completions is 500,000. If 1 million is actually completed, the completion rate should be, if 200,000 is completed, the actual completion rate is 20%, if 0 is completed, the actual completion rate is 0%, and if -500,000 is completed, then it should be:

Completion rate = (-50 100) * 100, that is, the completion rate is -50%.

How to calculate the completion rate when the base number is negativeThe formula completion rate = (2 - actual completion number of planned numbers) multiplied by 100% Note that this formula only applies to the situation where the planned number is negative, and how to calculate the completion rate when the plan is a negative number of travel townsHow to calculate the completion rate is a well-known analysis indicator, and the completion rate is equal to the percentage of the actual completion value to the target completion value. It is expressed in the male or town style as follows: completion rate Actual completion number Target completion number * 100%.

For example, if you want to memorize 20 words today, but you only remember 10 words, the completion rate is 50%. If the company asks you to sell 10,000 yuan a month, and you end up selling 12,000 yuan, your completion rate is 120%.

A completion rate is a percentage that indicates how far you've reached a goal or completed a task. To calculate the percentage of the achievement rate, you can use the following formula:

text ( left( frac}} good fight nucleus right) times 100 %

Silver Friends] Where:

The completed quantity is the number of tasks, projects, or objectives that you have completed.

The total quantity is the total number of tasks, projects, or goals that you originally planned or needed to complete.

Divide the completed quantity by the total quantity and then multiply the result by 100 to get the percentage of the achievement rate.

For example, if you plan to complete 30 quests and have completed 20 quests, then your friend's achievement rate is:

text (\left( \frac ight) \times 100\%

So, your achievement rate: This means that you have completed the planned task.

The achievement rate refers to the degree to which the actual value is compared with the target value, and is generally expressed as a percentage. There are two types of calculation methods and result judgments:

1. The larger the target disadvantages, the better: achievement rate = actual value target value. The higher the percentage value, the higher the degree of conformity, and greater than or equal to 100% is the achievement of the goal.

2. The smaller the target value, the better: achievement rate = 2 - actual value target value. The higher the percentage value, the higher the degree of conformity, and the goal is achieved if the infiltration is greater than or equal to 100%.

For example, if the planned completion is 100 and the actual completion is 50, the achievement rate = 50 100 100%, that is, the achievement rate is 50%.

If the planned completion is -100 and the actual rental is completed -50, the achievement rate = [2-(-50) (100)] 100%, that is, the achievement rate is 150%.
