using R, I want to get code and want to see a graph that shows observed frequency vs expected frequence with boxplot

2. Consider a discrete random variable with the following probability mass function 2 0 1 2 3 4 5 p(x) 0.1 0.1 0.2 0.3 0.2 0.1 Generate a random sample of size n = 10000 from this distribution. Construct a bar diagram of the observed frequencies versus the expected frequencies
