Which of the following pairs of sets are equals? Give reasons. (i) A={x:x is a letter of word FOWL} B={x:x is a letter of word WOLF} (ii) A=phi and B={x:x in N and 3x^(2)+3 lt 3} (iii) A={M,A,N}, B={W,O,M,A,N}

Which of the following are examples of empty set? {x : x^2-2=0\ a n d\ x is rational }

Select the pair of equal of equal sets from the following : A = {0} B = {x : x gt 15 and x lt 5, x in N} C = {x : x - 5=0} D = {x:x^(2) = 25} E = { x : x" is positive root of "x^(2)-2x-15}=0 .

State which of the following sets are finite sets or infinite. In case of finite set, mention the order of cardinal number (i) A=("x:x is a prime number and "x lt 15) (ii) B=(x:x in N, and 3x+2=11) (iii) C=(x:x in N and x^(2)-14x+3=0) (iv) D=(1,2,3,4....)
