# (a)A bit string is a finite sequence of 0’s and 1’s. how many bit strings have length 8? (b)How many bit strings of length 8 begin with three 0’s? (c)How many bit strings of length 8 begin and end with a1?

To determine

(a)

The number of bit strings that have length 8.

Explanation

Given information:

In a bit string that has length 8, each bit position has filled with either 0's and 1's.

Concept used:

Each position can be filled in two ways.

Calculation:

The total number of ways to accomplish the entire operation is the number of different bit strings of length 8

To determine

(b)

The number of bit strings of length 8 begin with three 0's.

To determine

(c)

The number of bit strings of length 8 begin and end with a1.
