In a bit string length 12 How many begin with 110?
You are essentially asking how many different bit strings of length 9 are there, as the first 3 bits are fixed. The answer is 2^9 = 512.
How many bit strings of length 8 are there which begin with a 0 and end with a 0?
-- 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.
How many bit strings of length 8 contain either three consecutive 0s or four consecutive 1s?
Five (5) have one or the other but not both. Six (6) have both. Total of eleven (11).
How many different bit strings are there of length 7?
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.
How many bit strings of length not exceeding n consist entirely of 1s?
n+1 (counting the empty string)
How many bit strings of length ten both begin and end with 1?
its 2 raised to power 8 i.e 256

How many bit strings are there of length eight?
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.
How many bit strings of length 10 have?
1024
How many bit strings are there of length ten?
210=1024
How many bit strings of length 8 ends with a 0?
Half of them.
How many strings does a parachute?
A parachute needs four strings. However, redundancy is best, both for safety and control of the chute. Thus, 16 striings is better, 32 even moreso. Washers around groups of strings cuts down on the likelihood of entanglement. The length of the strings matters, as well (and so does the diameter of the parachute).
How many strings of length 0 that start with 1 bit or end with 2 bits are possible?
There are no zero-length strings that start with 1 bit or end with 2 bits. In a zero-length string, there are no bits at all.
How many bit strings of length 8 contain either three consecutive 0s or four consecutive 1s?
Five (5) have one or the other but not both. Six (6) have both. Total of eleven (11).
How many bit strings of length 10 have more 0s than 1s?
There are 210.
How many bit strings of length 11 have more 0s than 1s?
1024 of them.
