Web5 sep. 2024 · Sets that are equivalent (under the relation we are discussing) are sometimes said to be equinumerous 1. A couple of examples may be in order. If A = { 1, 2, 3 } and B = { a, b, c } then A and B are equivalent. Since the empty set is unique – ∅ is the only set having 0 elements – it follows that there are no other sets equivalent to it. in a recession you would want the fed to https://boxtoboxradio.com
