Answer 2

Answer:

1956

Step-by-step explanation:

The number of signals with one flag = 6

The number of signals with two flags = $P_{2}^6$ = 30

The number of signals with three flags = $P_{3}^6$ = 120

The number of signals with four flags = $P_{4}^6$ = 360

The number of signals with five flags = $P_{5}^6$ = 720

The number of signals with six flags = $P_{6}^6$ = 720

6 + 30 + 120 + 360 + 720 + 720 = 1956
