How can i solve this probability problem in Matlab?

White blood cells are classified into 5 categories, one of which is neutrophil cells. Typically, there are 100 cells that fall into these categories. For a healthy adult the probability of finding neutrophils is 0.6. Determine the probability that a healthy adult will find between 50 and 75 (inclusive) cells.

The question seems to me to be ambiguous. Note that physiological variables are (essentially by definition) log-normally distributed. It would be necessary to know the parameters of that distribution to determine those probabilities.

i don t know how to explain better, this was the problem:White blood cells are classified into 5 categories, one of which is neutrophil cells.Typically, there are 100 cells for each category .For a healthy adult the probability of finding neutrophils is 0.6. Determine the probability that a healthy adult has beetween 50 and 75(inclusive) neutrophil cells.

I need to do this in Matlab...

[Star Strider]

It is certainly possible to do it in MATLAB.

The parameters of the logmnormal distribution that describe the probability density function (and therefore the cumulative distribution function) of neurtophils need to be provided. Once those are supplied, there are MATLAB functions (in the Statistics and Machine Learning Toolbox) that can provide the desired results.

This is all i have, i think i need a numeric value as a number, this problem came from Theory of probability, like Bayes, i will put here a formula for example, i think this problem need solve with this kind of formules
