Five (5) have one or the other but not both.
Six (6) have both.
Total of eleven (11).
The number of different bit strings of length 7 can be calculated using the formula 2^n, where n is the length of the bit string. In this case, with a length of 7, there are 2^7 = 128 different bit strings possible. This is because each bit in the string can have 2 possible values (0 or 1), and there are 7 bits in total.
-- There are 256 bit strings of length 8 . -- There are 4 bit strings of length 2, and you've restricted 2 of the 8 bits to 1 of those 4 . -- So you've restricted the whole byte to 1/4 of its possible values = 64 of them.

Length = 4, Width = 2
The factor strings for 12 is 6*2 , 2*2*3, 4*3 if you are doing a chart than you put the length is how long the problem.
Every bit can either be a 0 or 1. So to find the amount of bit strings of length either, you do 2length to find the amount of bit strings there are of a given length.
There are (2^5) bit strings of length 5, as each bit can be either 0 or 1. Therefore, the total number of bit strings is (32).
The total number of all binary strings that do not contain the substring "010" is 2n1, where n is the length of the binary string.
56 The number of triples of 1s on 8 bits
A bit string of length 10 consists of binary digits (0s and 1s). For each of the 10 positions in the string, there are 2 possible choices (either 0 or 1). Therefore, the total number of bit strings of length 10 is (2^{10} = 1024).
Character string values storage:1. CHAR:§ Stores strings of fixed length.§ The length parameter s specifies the length of the strings.§ If the string has smaller length it padded with space at the end§ It will waste of a lot of disk space.§ If the string has bigger length it truncated to the scale number of the string.2. VARCHAR:§ Stores strings of variable length.§ The length parameter specifies the maximum length of the strings§ It stores up to 2000 bytes of characters§ It will occupy space for NULL values§ The total length for strings is defined when database was created.3. VARCHAR(2):§ Stores strings of variable length.§ The length parameter specifies the maximum length of the strings§ It stores up to 4000 bytes of characters§ It will not occupy space for NULL values§ The total length of strings is defined when strings are given

To find the number of bit strings of length 10 that begin and end with "1", we fix the first and last bits as "1". This leaves us with 8 bits in the middle, which can each be either "0" or "1". Therefore, there are (2^8 = 256) different combinations for the 8 middle bits. Thus, there are 256 bit strings of length 10 that begin and end with "1".

Yes, an instrument that produces sound by vibrating a string or strings is classified as a string instrument. This category includes instruments like violins, guitars, and cellos, which generate sound through the vibration of their strings, either when plucked, bowed, or struck. The pitch is typically altered by changing the tension, length, or mass of the strings.
By the sum rule we can count the number of strings of length 4 or less by counting the number of strings of length i, for 0 <= i <= 4, and then adding the results. Now there are 26 letters to choose from, and a string of length i is specified by choosing its characters, one after another. Therefore, by the product rule there are 26^i strings of length i. The answer to the question is thus: sum i=0 to 4 ( 26^i = 1 + 26 + 676 + 17576 + 456976) = 475,255.
