If `u={x:x in N` and `2<=x<=12`} , A={x: x is an even prime }, B={x: x is a factor of 24} then

If U= {x|x in N, x lt 10} , write the union of the following set A = {a|a in U, a is an even number}

If U={x:x<=10,x in N} is the Universal set, A={x:x in N,x is prime number } and B={x:x in N, x is even} write A n B in roster form.

If U = {x|x in N, xlt 8 } , write the union of the following sets: A={a|a in U, a is an odd number } and B= {b|b in U, b is a divisor of 4} ,

If U= {x|x in N, x lt 10} , write the union of the following set B ={b|b in U, b is a divisor of 6}

If U = {x:xle 6 and x in N}, A = {3,5} , B={2,5,6} then (A cup B) ?

U= [-2,1], A= {x : x in N, x^(2)+x -2=0} then A'="………." .

If U={x:x inNN,xle10} , A = {2, 3, 4, 8, 10} and B = {1, 2, 5, 8, 10}, then verify that n(AcupB)=n(A)+n(B)-n(AcapB)

Find the cardinal number of the following sets (i) M={p,q,r,s,t,u} (ii) P={x: x=3n+2, n in W and x lt 15} (iii) Q={y: y=(4)/(3n), n in N and 2 lt n le 5} (iv) R={"x : x is an integer, "x in Z and -5 le x lt 5} (v) S= The set of all leap years between 1882 and 1906.

U_(n)=int_(0)^(1)x^(n)(2-x)^(n)dx and V_(n)=int_(0)^(1)x^(n)(1-x)^(n)dx,n in N and if (V_(n))/(U_(n))=1024, then the value of n is
