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).
