Ways to choose colors = 5C3 = 10
Ways to arrange these colors = 3! = 6
Ways of arrangement (vertical or horizontal) = 2
Number of ways = 10*6*2 = 120

The flag has to contain THREE different colour strips, and can be positioned either Horizontally or Vertically.
We have 5 different colours - green, red, yellow, black, and blue.
We need to choose three colours out of Five different colours = 5C3 = 10 ways.
Arrange the colours = 3! = 6 ways.
Positioning is done in two ways = Horizontal or Vertical = 2 ways.
Total number of Ways = 10*2*6 = 120 ways.
