Question 998208
<font face="Times New Roman" size="+2">
The probability of *[tex \Large k] successes in *[tex \Large n] trials where *[tex \Large p] is the probability of success on any given trial is given by:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ P_n(k,p)\ =\ {{n}\choose{k}}\left(p\right)^k\left(1\,-\,p\right)^{n\,-\,k}]


Where *[tex \LARGE {{n}\choose{k}}] is the number of combinations of *[tex \Large n] things taken *[tex \Large k] at a time and is calculated by *[tex \Large \frac{n!}{k!(n\,-\,k)!}]


To find the probability of at least 1, you need 1 minus the probability of Zero.  Unless you are a glutton for punishment in which case you can add the probability of 1, plus the probability of 2, plus the probability of 3, and so on through 6.


You want zero successes in 6 trials with a constant probability per trial of 0.02, then subtract from 1.

My calculator said it, I believe it, that settles it
