## Binomial, poisson, and gaussian dstributions

bincomp.m Graphical comparison of the binomial, Poisson, and Gaussian distributions. The procedure calls for binomial parameters $n,p$ , determines a reasonable range of evaluation points and plots on the same graph the binomial distribution function, thePoisson distribution function, and the gaussian distribution function with the adjustment called the “continuity correction.”

## Setup for simple random variables

If a simple random variable X is in canonical form, the distribution consists of the coefficients of the indicator funtions (the values of X ) and the probabilities of the corresponding events. If X is in a primitive form other than canonical, the csort operation is applied to the coefficients of the indicator functions and the probabilities of the corresponding events to obtainthe distribution. If $Z=g\left(X\right)$ and X is in a primitive form, then the value of Z on the event in the partition associated with t i is $g\left({t}_{i}\right)$ . The distribution for Z is obtained by applying csort to the $g\left({t}_{i}\right)$ and the p i . Similarly, if $Z=g\left(X,Y\right)$ and the joint distribution is available, the value $g\left({t}_{i},{u}_{j}\right)$ is associated with $P\left(X={t}_{i},Y={u}_{j}\right)$ . The distribution for Z is obtained by applying csort to the matrix of values and the corresponding matrix of probabilities.

I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
