If `{p in N: "p is a prime" and p=(7n^(2)+3n+3)/(n)"for some n" in N}'` then the number of elements in the set A, is

If A={ p in N,p is a prime and p=(7n^(2)+3n+3)/(n) for some n in N ), then the number of elements in the set A is

If a set P has n elements, then the number of elements in the power set P is:

If A={p:p=((n+2)(2n^(5)+3n^(4)+4n^(3)+5n^(2)+6))/(n^(2)+2n), n p in Z^(+)} then the number of elements in the set A, is

If A={p:p=((n+2)(2n^(5)+3n^(4)+4n^(3)+5n^(2)+6))/(n^(2)+2n), n p in Z^(+)} then the number of elements in the set A, is

If n lt p lt 2n and p is prime and N=.^(2n)C_(n) , then

If n lt p lt 2n and p is prime and N=.^(2n)C_(n) , then

If n lt p lt 2n and p is prime and N = .^(2n)C_n , then

If 'P' is a prime number such that p ge 23 and n+ p! + 1 , then the number of primes in the list n+ 1, n+2 , ….. , n+p-1 is

A and B are two that n(A) gt n(B) . P(A) and P(B) are power sets of A and B respectively and the difference between cardinal numbers of P(A) and P(B) is a three digit prime number. The number of elements in set A is "______" .

A and B are two that n(A) gt n(B) . P(A) and P(B) are power sets of A and B respectlively and the difference between cardinal numbers of P(A) and P(B) is a three digit prime number. The number of elements in set B is "______" .
