Let X be a discrete random variable with probability mass function given by 1/4 x = 0 1/2 x = 1 1/8 x = 2 1/8 x = 3 p(x) = a. Use sample to create a sample of size 10,000 from X and estimate P(X = 1) from your sample. Your result should be close to 1/2. b. Use table on your sample from part (a) to estimate the pmf of X from your sample. Your result should be similar to the pmf given in the problem.

Question

This is a Statistics problem. Please explain each step thoroughly.

The problem I'm having issues with is shown below:

 

Let X be a discrete random variable with probability mass function given by 1/4 1/2 p(x) = 1/8 1 x = 2 1/8 x = 3 a. Use sample to create a sample of size 10,000 from X and estimate P(X = 1) from your sample. Your result should be close to 1/2. b. Use table on your sample from part (a) to estimate the pmf of X from your sample. Your result should be similar to the pmf given in the problem.
