## What is Binomial Distribution PRO?

The binomial distribution is a discrete probability distribution. To calculate it needs the probability of a single experiment, hits and trials. The app shows all important quantities step by step and provides the histogram of the binomial distribution and distribution function chart. You can choose between success probability and complentary probability.

Depending on variable, natural numbers or decimal numbers are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared.

[ Contents ]
- binomial distribution with success probability and complementary probability
- probability p, hits k and trials n must be entered
- expected value, variance, standard deviation are calculated
- results are calculated and shown in detail
- histogram and distribution function chart
- history to save the input
- detailed solution
- natural or decimal numbers are supported
- no ads!

[ Usage ]
- there are fields for entering values using a special keyboard
- press the check mark button at the bottom right to start the calculation
- if values are missing, the corresponding field is highlighted in yellow
- if the values are incorrect, the affected field will be highlighted in red
- a short message explains why a value is incorrect
- the entries in the history can be deleted or sorted
- if you select an entry in the history, it will be automatically loaded for the calculation
- the whole history can be deleted by pressing a button
- solutions can be shared
- p must be greater than 0 and less than 1
- k must be greater than or equal to n


## Version history (last 5 releases)

### 2.3.2 — 2026-08-04

- the status bar on top is integrated into the current app design
- the app flow was improved (pop-up information was balanced)

### 2.3.1 — 2026-07-17

Maintenance update. Improving performance.

### 2.3.0 — 2026-06-19

Bringing all apps to the same security standard. Critical storage behaviour for solutions has been fixed.

By the way - I run many apps with different math topics. If you like this one: Check them out as well!

I always do my best to keep a high standard on my apps. If something does not meet the expectations, do not hesitate to contact me.

### 2.2.10 — 2026-06-06

为了让解题保存和加载更加稳定，我们进行了大量修复和调整。因此，后台进行了部分数据库修改。不会有性能损失，功能也不会发生变化。后台任务仅执行一次，并在几毫秒内完成。可能会出现以下情况（仅暂时）：
- 已保存的计算可能需要点击两次才能完全加载
- 已保存解题的顺序可能发生变化

如果出现解题丢失，请随时联系我，并告诉我丢失的解题数量 + 受影响的应用。我会找到解决方案。

此致，Alex（开发者）

### 2.2.9 — 2026-05-01

Minor improvements. New crash report system so that maintenance work is much more efficient.
