This application easily calculates the probability information you are curious about when you are doing a car.

It can be used in the following situations:

"How many times do I have to take out an SSR card with a 0.7% probability?"
"How many R-rated characters can we expect to have if we turn 100 years away?"
"How many times do I have to take a Gacha to get about 30 items rated SR?"


The calculation modes currently supported are as follows:
[Single Target]
This mode calculates this and that probability events that occur in order to pick one target.

[Single Target Multiple Pull]
It calculates this and that probability event that happens to select one target multiple times.

* Calculation mode will be added in the future
