Answer 2

Answer:

The bit strings of length 7 have 64.

Step-by-step explanation:

If a string carries k 1’s then there could be 7-k 0’s could be there.

the quantity of strings with k 1’s and 7-k 0’s is 7!/(k!)(7-k)!

the maximum value of k is 3.

if we expect the minimum value of k is 0, then we've got the full quantity of strings is

= (7!/0!7!) +(7!/1!6!)+(7!/2!5!)+(7!/3!4!)

=1+7 +21+35

=64

if we expect the minimum value of k is 1, then the quantity of strings is = =7+21+35

=63.
