Consider the sets. A= {distinct letters in the word keep} B = {13} C = {k, e, p} D= {2 + 1} E = {three} F = {3} (a) What is the cardinality of each set? |A| = |B|= ICI = ID= = IE= IFI (b) Which of the sets are equivalent? OA C D; E F OA C; D E F OA C; B D E F OA B; CD; E F OA C B D E F (c) Which of the given sets are equal? OA=C=D; E = F A=C=D=E=F C=E=F OA=C; D=E=F OA=C; B=D=E=F
