Two red bottles, two yellow bottles, and one blue bottle are to be arranged in a straight line from left to right on a windowsill. How many different unique arrangements are possible?

A. 30
B. 24
C. 12
D. 10
E. 4

There arrangement comprises five bottles

5!

There are 2 red bottles, 2 yellow bottles and 1 blue bottle

2!, 2!, 1!

Total Arrangements/ # Factorials = # of repeating items (I think)

5!/2! x 2! x 1!
