Answer:
C) 15
Step-by-step explanation:
Given,
Total number of colours = 3,
Ways of choosing three flags of a colour = 3,
Ways of choosing three flags of two colours = 3 × 2 = 6,
Ways of choosing three flags of three colours = 3 × 2 × 1 = 6,
Hence, the total number of possible ways = 3 + 6 + 6 = 15
i.e. OPTION C is correct.
