is the distribution a discrete probability distribution? Why? Choose the correct answer below 

   

A. Yes because the distribution is symmetric

  B. No because some of the probabilities have values greater than 1 or less than 0 

 C. No because the total probability is not equal to one 

D. Yes because the probabilities sum to one and are all between 0 and 1 inclusive
