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.

Here are all the twin primes between 100 and 200.(101, 103), (107, 109), (137, 139), (149, 151), (179, 181), (191, 193), and (197, 199).Twin primes are prime numbers that differ from each other by 2.

170 and 190 are composite numbers, not primes. Twin primes are pairs of prime numbers that differ from each other by two. Examples of all twin primes less than 200 are (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), (71, 73), (101, 103), (107, 109), (137, 139), (149, 151), (179, 181), (191, 193), and (197, 199).

Not true. 2 + 3 = 5, where all three are primes. One of the primes in the sum must be 2, otherwise both primes would be odd and their sum would be even (and >2) and therefore not prime. Such primes: p and p+2 [3 and 5 in the above example] are known as twin primes and there are infiitely many twin primes.

There is no known prime formula to identify all primes. There are some formulae that work only for some classes of primes. Mathematicians have

There are an infinite number of pairs of prime two apart, classified as "twin primes". For lists, see the link.

Yes. If all the question's parts are true, then the answer is true. If all the question's parts are false, then the answer is false. If one of the question's parts is false and the rest true, then the answer is false. Logically, this is illustrated below using: A = True, B = True, C = True, D = False, E = False, F = False A and B and C = True D and E and F = False A and B and D = False If you add NOT, it's a bit more complicated. A and NOT(D) = True and True = True NOT(D) and D = True and False = False NOT(A) and NOT(B) = False and False = False Using OR adds another layer of complexity. A OR NOT(E) = True OR True = True NOT(D) OR D = True OR False = False NOT(A) OR NOT(B) = False OR False = False Logic is easy once you understand the rules.
