How to combine several variables into a single variable is a FAQ. Variables can be combined in SPSS by adding or multiplying them together. For n independent trials each of which leads to a success for exactly one of k categories, with each category having a given fixed success probability, the multinomial distribution gives the probability of any particular combination of numbers of successes for the various categories.
