In this question, Suzan is taking 5 marble from a bag containing four red marbles, four green ones, two white ones, and two purple ones. The total marble in the bag should be: 4+4+2+2 = 12. The question is how much the probability to get two red, 1 green, 1 white and 1 purple. Then the probability would be:

4*3*4*2*2 / 12*11*10*9*8 = 192 / 950400 = 1/495
