The U. S. Department of Justice examined all reported cases of identity theft for U. S. residents aged 16 or older. Their data show that of all the reported incidents of identity theft in a recent year, 40% involved existing credit card accounts. You are to design a simulation of seven reported identity thefts showing which ones involve existing credit card accounts and which ones do not. How would you assign the random digits 0 through 9 to the two categories "Does" and "Does not" involve existing credit card accounts?
