n(A)=4 then n(p(A))=…………

If two sets P and Q ,n(P)=5 ,n(Q)=4 then n(P xx Q)=

Find n when ""^(n-1)P_(4): ""^(n)P_(5)=1:9 , then n = …………….

If n(A) = 4, find n[P(A)].

(i) If n(A)=4, find n[P(A)] (ii) If n(A)=0, find n[P(A)] (iii) If n[P(A)]=256, find n (A)

If .^(n)C_(4)=35 , then .^(n)P_(4)= ____

P={x:x is a multiple of 4, x lt 20 } and Q= {xx is a multiple of 6,x lt 30 } Find n(P) +n(Q). The following steps are involved in solving the above problem .Arrange them in sequential order .(A) P= {4,8,12,16} and Q={6,12 , 18,24} (B) rArr n(P) =4 and n(Q)=4 (C ) n(P) = 4 and n (Q) =8

if P(n)=n+4 the what is P(n)+P(-n)=?
