A simple case rating calculator for Warframe or other video games. Here is the table for resetting the war frames.

**Planned**

**Work**

**90% chance**- achieve at least one success
- go back in time
- an equal chance of losing a race

**Almost guaranteed**

**Work**

**99% probability**- achieve at least one success
- go back in time
- an equal chance of losing a race

**Facts**

**% for race**

- the chance of getting a number in a test drive
- 10 passes, % probability
- 20 passes, % probability
- 30 passes, % probability
*Successful at least once*

**Make no mistake about the risk of a fall**

One of the most common misconceptions about the probability of a decrease is that the percentage is taken for granted:

- A 10% probability of a fall means
**instead of**, where*means every tenth repetition of*. - A 10% probability of
**falling in place of**means that a*of 100*attempt will be successful. - A 10% chance of falling only means that
*will fall on a fairly large sample of*or tens of thousands of attempts – about 10% of these attempts will succeed.

And since we’re talking about coincidence, if you fall 10%, there’s a chance you’ll fail 900 times before you pass the next 100. That’s the beauty of coincidence.

**Mathematics used**

The calculation of the number of attempts to achieve at least one positive result is based on the probability of failure:

The probability of a 10% decrease means a 90% (0.9) failure probability.

This means that the probability of failure for 10 consecutive passes is 0.9^10 = 0.3486784401.

Rounded to two decimal places we now have a failure probability of 0.35 or 35%.

And that means another 65% chance of success (at least once) in 10 races with a 10% chance of decline.
