Dear co-listers. I found an exercise about probabilities (it supposed to be about multinomial experiments) that I can't resolve. Maybe you can help me to find solution and the way to solve it. The problem says: A dice is thrown up 4 times. What is the probability of not obtaining a 1, neither 2 or neither 3. Thanks for your help. ______________________________ Rodrigo Briceņo Consultor Sanigest Internacional Telf. Oficina: (506) 291-1200 Fax. (506) 232-0830 Telf.
