A={x:x in W,x<5}

Write each of the following sets in Roster form and write the cardinal number of each . D = {x: x in W, x- 3 lt 2 }.

State in each case, whether the given statement is true or false : If D ={ x: x in W, x lt 4 }, then n(D) = 4.

Identify whether the given pair consists of equal or equivalent but not equal sets or none: C = {x: x in N, x + 5 = 6 } and D = {x:x in W, x lt 1 }.

State in each case, whether the given statement is true or false : { x: x in W, x +5=5} is a singleton set.

Find all the subsets of each of the following sets : (i) A={5,7}, (ii) B={a,b,c} (iii) C={x, x in W, x le 2} , (iv) {p:p is a letter in the word 'poor'}

B={x :x in W " and " 5x-3 le 20}

M = {x | x in W, 3x + 6 = 0} is a

Which of the following sets are equal? : P = {x | x in W, x is a multiple of 2} : Q = {x | x is an even number, x > 1} : R = {x | 2x = n, n in N}

If A {x | x in N , x is a multiple of 4 and x lt 25 } and B = { x| x in W , x is a multiple of 6 and x lt 25 } , then show the relationship between these sets by a Venn diagram .
