"Thank you!" to both Johannes Ludsteck and Kenneth Levasseur, who 
supplied me with solutions to my query.

As Johannes pointed out, the Statistics`MultiDiscreteStatistics` 
package has facilities for drawing random numbers from a multinomial 
probability distribution. However, I personally prefer Ken's solution:

RandomIndex[m_] :=
(m /. {{a__, b___} :> Length[{a}] /; Plus[a] >= #}) &[Random[]]

Once again, thank you both.
Wagner
