### • Given:– 5 flags of different colours 2 flags required for Signal

### SOLUTION:- Number of flags possible for upper flag =  One of the flag is taken, therefore, the number of flags remaining for lower flag in the signal is  The number of ways in which signal can be given  ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Therefore, different signals can be generated if each signal requires the use of 2 flags, one below the other.

━━━━━━━━━━━━━━━━━━━━━━━━━ ➡️Given 5 flags of different colours

Given 5 flags of different coloursWe know the signal requires 2 flags.

➡️The number of flags possible for upper flag is 5.

➡️Now as one of the flag is taken, the number of flags remaining for lower flag in the signal is 4.

➡️The number of ways in which signal can be given = 5 × 4 = 20.  ━━━━━━━━━━━━━━━━━━━━━━━━━
