There are 731 pairs.
25. any number in half equals how many twin primes. so 50/2 =25 EX.1-2 =1 1-10 = 5
As numbers get larger, there are more chances that a number will be a multiple of something other than 1.
25 of them.
There are 19 primes.
All pairs of two primes are coprime. There are fifteen primes under 50. So that means there are 105 unique pairs of "coprime primes", or more generally, pairs of primes, under 50.
There are 731 pairs.

The only consecutive primes between 1 and 100 are 2 and 3.
As numbers get larger, there are more chances that a number will be a multiple of something other than 1.
25 of them.
Any number greater than one can be co-prime. I guess the answer is 49.
There are 9592 primes.
There are 19 primes.
The primes between 1 and 10 are:2, 3, 5, 7The primes between 1 and 10 are:2, 3, 5, 7The primes between 1 and 10 are:2, 3, 5, 7The primes between 1 and 10 are:2, 3, 5, 7
There are for pairs of co-primes between 1 and 25. They are (3, 5), (5, 7), (11, 13), and(17, 19).
There are 168 primes between 1 and 1000 and 1229 between 1 and 10,000.
