420 different signals can be transmitted.
Total number of blue flags = 2
Total number of red flags = 2
Total number of yellow flags = 4
Therefore,
Total number of flags = 2 + 2 + 4 = 8
Number of flags on the pole simultaneously -
= (8!/2! 2! 4!)
= (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (2 × 1 × 2 × 1 × 4 × 3 × 2 ×1)
= 40320/96
= 420
= 420 signals
Thu, 420 signals can be transmitted.
