## Most Probable Number calculation

Therefore, the probability of obtaining a fertile sample, , is. If samples of volume are taken, the probability observing fertile samples is given by the binomial distribution as. What we want to know is the “most probable number (MPN)”, the density which maximizes the probability of obtaining the observed result.

## Calculation of Joint Moments and Muscle Forces - Ma

If the distance from the ankle joint centre the foot centre of gravity is measured as 0.05 m and the distance from the ankle joint centre to the reaction force R is 0.20 m, then it is possible to calculate the moment about the ankle joint centre. Taking moments about the ankle joint centre: Ma = (0.20 x R) – (0.05 x mg)
