25 pairs, including the pair (2, 3).
25. any number in half equals how many twin primes. so 50/2 =25 EX.1-2 =1 1-10 = 5
There are 95 primes in the specified range.
False. Co-primes are not the same as twin primes.Co-primes are any numbers having no common factorsother than 1. Examples of co-primes are 8 and 9 or 15 and 32.Twin primes are pairs of prime numbers exactly 2 apart such as 11 and 13 or 659 and 661.
There are eight twin primes between 1 and 100. They are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), and (71, 73).

The question depends on what it is that you want to prove!
Actually, 13 and 15 are not twin primes because twin primes are pairs of prime numbers that have a difference of 2 between them. In this case, 13 is a prime number, but 15 is not a prime number because it can be divided by 3 and 5 in addition to 1 and itself. Therefore, 13 and 15 do not meet the criteria to be considered twin primes.

Any number greater than one can be co-prime. I guess the answer is 49.

There are 169 primes that are smaller than 1000.
