# Geometric distribution (chart)

## Calculates a table of the probability mass function, or lower or upper cumulative distribution function of the geometric distribution, and draws the chart.

 select function probability mass f lower cumulative distribution P upper cumulative distribution Q probability of success p 0≦p≦1 [ initial percentile x(failure number) before success increment repetition ]
 $\normal Geometric\ distribution\\[10](1)\ probability\ mass\\\hspace{30}f(x,p)=p(1-p)^x\\(2)\ lower\ cumulative\ distribution\\\hspace{30}P(x,p)={\large\sum_{t=0}^{x}}f(t,p)\\(3)\ upper\ cumulative\ distribution\\\hspace{30}Q(x,p)={\large\sum_{t=x}^{\infty}}f(t,p)\\$
