4. because each flip flop counts to 3
If counting in binary, 12 flip flops If counting in decimal (BCD), 15 flip flops (3, 4, 4, 4)
(2^5) = 32 SO, 5 flipflops are required to produce a divide by 32 device
It takes nine flip flops to count from 0 to 511.
3 flip flops are required.
flip flops were made to pretect your feet they where also made to wear to the beach actually there are many answers to this question
