i thought since there were 2 answers for every question thats 30 answers total so the final answer to the question would be 30 choose 15. Each question can be answered in 2 ways.
How many possible answer sheets are there?
1 Expert Answer So there are 2757 = 107 = 10,000,000 different possible answer sheets. HOWEVER… It’s possible, isn’t it, that someone could leave an answer blank. In a sense, that counts as one more possible answer for each question.
How do you answer how many questions?
To answer a question that asks “how many,” use a number or a quantity description with a plural noun. Use many or few with count nouns….Note: “A few” is different than “few.” “Fewer than” is comparative.
- “A few” means several.
- “Few” means not many.
- “Fewer than” compares the quantity of something to something else.

How many combinations of initials are there?
If the first initial is B, the pair of initials could be BA, BB, BC, ., BZ. Again there are 26 different pairs. Continuing in this way and since there are 26 possible first initials, each of which could be paired with 26 last initials, there are 26 × 26, or 676 possible different pairs of initials.
How many different 3 letter initials are there that begin with an A?
676 different three-letter initials beginning with an A.
How many ways May 4 cards be drawn randomly from a deck of 52 cards?
1108
How many different three-letter initials are there that ends with AC?
17,576 different three-letter initials.
How many bit strings of length ten begin and end with a 1?
256 bit strings
How many bit strings are there of length eight?
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 bit strings of length eight both begin and end with a 1?
How many bit strings of length 8 begin and end with a 1? My answer would be: 26. Because we know, that the bit starts with 1 and ends with 1: Which means, that 2 of the length 8 is used, also there are 6 positions remaining, which is 26=64.
How many different bit strings of length 7 are there?
I am thinking for the strings that start with 10, we would have 7−2=5 bits to choose, so 32 possible bit strings of length 7 that starts with 10.
How many bit strings of length 8 contains either three consecutive 0s or four consecutive 1s?
Those are 11110000, 11110001, 11111000, 01111000, 00011110, 00011111, 00001111, 10001111 i.e. 8 strings we have double counted. So, total number of bit strings of length eight containing either three consecutive 0’s or four consecutive 1’s = 107 + 48 – 8 = 147 (answer is 147, not 145).
How many bit strings are there of length 4 that do not have any consecutive 1’s?
I came across following problem: How many bit strings of length four do not have two consecutive 1s? However the correct solution turns out to be 8.
How many 8-bit strings have at least two consecutive 0’s or two consecutive 1’s?
The total number of 8-bit strings with no restrictions is 2^8. Therefore the number of 8-bit strings which have at least two consecutive 0’s or at least two consecutive 1’s is 2^8 – 2.
How many 8-Bit string of 0’s and 1’s of length 8 are there that contain exactly three 0’s in a row and five 1’s?
How many 8-bit strings contains three 0’s in a row and five 1’s? Answer = 6!/5! #63 – 66 refer to a shipment of 50 microprocessors of which four are defective.
How many bit strings of length 10 contain an equal number of 0s and 1s?
= 210. 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. = 10!/(0!
How many bit strings of length n are palindromes?
The numbers of bit strings of length n that are palindromes are: 2n2 2 n 2 if n is even.
How many 10 bit strings contain 6 or more 1’s?
386 strings
How many permutations of the letter Abcdefg are there?
Given the string ABCDEFG there are 7! different permutations of that string. Given the string ASEFG there are 5!= 120 different permutations of that string.
How many 10 bit strings are there?
384 strings
What is a bit string?
A bit string is a sequence of bits. Bit strings can be used to represent sets or to manipulate binary data. This number is an exact non-negative integer that is fixed when the bit string is created. The valid indexes of a bit string are the exact non-negative integers less than the length of the bit string.
