The number of different signals consisting of 7 flags that can be made using 3 white flags, 2 red flags, and 2 blue flags is 24.
Since a signal can be formed by running different colored flags up a pole, one above the other, to find the number of different signals consisting of 7 flags that can be made using 3 white flags, 2 red flags, and 2 blue flags the following calculation must be performed:
- 3 x 2 x 1 x 2 x 1 x 2 x 1 = X
- 6 x 2 x 2 = X
- 12 x 2 = X
- 24 = X
Therefore, the number of different signals consisting of 7 flags that can be made using 3 white flags, 2 red flags, and 2 blue flags is 24.
