Question is that "Random variable for μ = 10, σ2 = 10.Calculate n and p values for a binomial distribution to be approximated as normal distribution for the above normal distribution mean and variance."
When I do research on the internet, they tell me to use the binofit function to calculate the n and p values. But in each sample made with binofit, n and p values were made knowing. Since the question asked me to calculate the n and p values, I could not find a solution. Can you help me?

The question has nothing to do with Matlab.
Just recall, that in the binomial distribution μ=n*p and =n*p*(1-p).

If μ = 10, σ2 = 10, than the solution of the equations {n*p==10, n*p*(1-p)==10} is and . In fact, this limit is the Poisson distribution with μ = 10. No binomial distribution with finite n and p can possess such properties.
