Chance of arrival before the limit

—

Exponential model assume constant hazard and waiting time wey no depend on past waiting.

Formula

P(T≤t)=1−e⁻ᵗᐟᵐ

Estimate chance say event go happen before waiting time reach the limit.

Example wey show the calculation

Waiting time on average
10
Waiting-time limit
5
Chance of arrival before the limit
39.3469340287 %
Chance say person still dey wait at the limit
60.6530659713 %

Where e fit work and limits

Exponential model assume constant hazard and waiting time wey no depend on past waiting.

We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.

Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
