Subset
A = {x : x is a letter in the word SEAT}
B = {x : x is a letter in the word TASTE}

Not equal because seat has 4 letters and taste has 5 letters.
Equivalent because they have the same letters
Equal because each set has the same cardinality and the same letters.
set V = { m, n, o, p },
find the number of subsets V.
