You will do factorial in this question..
There 9 places as the sum of the number of tulips are 9.
You'll do 3 different calculations for 3 different colour..
(number of places)! / [(number of tulips in same colour)! * (number of places - number of tulips in same colour)!]
Start with red ones..
9! / [2! * (9-2)!] = a is the number of possibilities for red ones..
Continue with yellows but now you have 9-2=7 places left as you used 2 of them.
7! / [3! * (7-3)!] = b is the number of possibilities for yellow ones..
Continue with purples but now you have 7-3=4 places left as you used 5 of them.
4! / [4! * (4-4)!] = c is the number of possibilities for purple ones..
The total possibility in this question is the the multiplication of a*b*c
