16. For numbers 17-21, refer to the given sets below, determine the elements of the sets that follow. Given: A = {1, o, v, e} B = {f, a, i, t, h) C={h, o, p, e) 17. AUB = { a. {l,o,v,e,f.a,i.t,h) b. {f, ait,ho,p,e} c. {1,0,0,e,h,o,p) 18. BUC = a. {1,0,v,e,h,o,p} b. {1,0,0,e,f, a, i,t,h} c. {f, a.i.t,h,o,p,e) 19. Anc = { a. {o,e} b.) c. {h} 20. BnC=U a. {o.e] b. c. {n} 21. AnB = { a. {o,e) b.) c. {h)​
