How many bit strings of length 8 are there?

How many bit strings are there of length 8? There are 28 which is 256. That means there are 256 different values you can store in a byte, since a byte is eight bits.

How many strings of length 8 either begin with 3 zeros or end with 4 ones?

So total n1=6⋅25 but here you can have 8 ways to get 4 consecutive 1s.. In same way for Case 2. n2 will be 5⋅24 and here also we can find 8 ways to get 3 consecutive 0s. Thus total =n1+n2−(8+8)=272−16=256.

How many bit strings of length 8 have the same number of 0s and 1s?

When you have chosen were to place the 0’s in the bit string the indices of the 1’s are automatically determined. You have (84) possibilities to place the 0’s, and therefore (84) possible strings with equal number of 0’s and 1’s.

How many binary strings of length Ten have exactly three 1’s somewhere within the string?

912 strings
Summary: 912 strings of length 10 contain at least three 1s and at least three 0s.

How many bit strings of length 8 contain I exactly four 1’s in an equal number of 0’s and 1’s?

Here, n = 5 and r = 2. So there are 10 bit strings of length 5 with exactly two 1’s in them.

What is an 8-bit string?

A byte is a string of 8 bits.

How many bit strings of length 8 either start with a 1 or end with 00?

160
Number of bit strings of length 8 that start with 1 and end with 00: 25 = 32. Applying the subtraction rule, the number is 128 + 64 − 32 = 160.

How many bit strings of length Ten contain at least three 1’s and at least three 0’s?

1024 – 1 – 1 – 10 – 10 – 45 – 45 = 912. Therefore, 912 strings of length 10 contain at least three 1s and at least three 0s.

How many binary strings strings consisting of 0s and 1s of length 10 are there that contain exactly six 0s?

There are 10! ways to place the ones and zeros. But as the zeros are interchangible and for any pattern of ones and zero there are 6!

How many bits string of length 4 are possible such that contain two ones and two zeros?

3. How many bits string of length 4 are possible such that they contain 2 ones and 2 zeroes? Explanation: The strings are {0011, 0110, 1001, 1100, 1010 and 0101}. 4.

How many bit strings of length 10 contain a Exactly four 1’s B at most four 1 s/c at least four 1’s d an equal number of 0 s and 1 s?

b) at most four 1s? We add up the number of bit strings of length 10 that contain zero 1s, one 1, two 1s, three 1s, and four 1s. 1 + 10 + 45 + 120 + 210 = 386.

How many 8 bit strings can be constructed such that first digit is 1 or the last digit is 1?

Case 1: First binary digit is 1. Given this condition, all possible strings with attribute fulfill the required ‘Or’ condition. So there are 27 strings in this set.

How many binary strings of length 8 are there that contain two or fewer 1s?

Therefore, there are 37 binary strings.

How many bit strings of length 10 either begin with 3 zeros or end with 3 ones?

Total: 2^5 x 2^1 x 1×2^2 = 32 x 2 x 4 = 256.

How many bit strings of length 12 contain an equal number of 0’s and 1’s?

(d) An equal number of 0s and 1s in a string of length 12, means that there are six 0s and six 1s.

How many bit strings of length 5 are possible such that contain two ones and three zeroes?

Then how many such bit strings are possible? Explanation: The total strings are 1(having no one in it) +5(having 1 one in it) +10 (having 2 ones in it) = 16. 5.

How many 8 bit strings can be created if the 1st bit is 1 or the last bit is 1?
