i need help with this question.    A delivery driver has three packages left in her truck that she must deliver before she is done for the day. She knows the three addresses remaining on her list, but the packages themselves have defective address labels that cannot be read. Because she is eager to get home, she decides to randomly select one package for each address. Let X represent the number of addresses that receive the correct package.  (a) Create a probability table to represent the probability distribution of X? Hint: List the different ways can she deliver the three packages.  (b) What is the expected number of addresses that receive the correct package?
