For the given sets, construct a Venn diagram and place the elements in the proper region. Let U = {b, e, g, f, k, q, t}A = {e, g, f, q}B = {b, e, g, t}

Determine whether the statement is true or false.  3 ∈ {1, 3, 5, 7, 9}

Fill in the blank with either ∈ or ∉ to make the statement true.  0 _____ ∅
