Statistics in Rstudio

Hypothetical case: This is a forest that I divided into 10 regions, the probability of finding a species of tree in this area is 0.3

n <-10 #number of regions
p <- 0.3#probability of success in each trial

How I can calculate and plot the density function and find the mean and variance of the random variable?

In terms of probabilities, how I can find 6 or more regions with trees? How I can do it or with what function?

Did you read my answer to your other question? Same method.
