Construct a truth table to decide if the two statements are equivalent. 21) -p a -q; ~(p v q) A) True 21) B) False Tell whether the statement is true or false. 22) 7 « (14, 21, 28, 35, 42} A) True 22) B) False Determine whether the given set is disjoint or not disjoint. Consider the set N of positive integers to be the universal set, and let A = {n « N[ n > 50} B = {n « N] n < 250} O= {n « N] n is odd} E = {n « N[ n is even} 23) A' ^ B' A) disjoint 23) B) not disjoint

22 ) good handwriting please

what is the cardinal number of the set {1, 3, 7, 4, 22, 16, 12}? Where denotes the set of all natural numbers.

Can you check if i did this correct
