Use ⊆​, ⊈​, ⊂​, or both ⊂ and ⊆ to make a true statement.   ​{a,b}    ​{z,a,y,b,x,c}

Write or in the blank so that the resulting statement is true. {t, h, e, c, o, u, n, t, r, y, s, i, d, e} {t, h, e, c, o, u, n, t, r, y, s, i, d, e} {n, o, c, i, t, y, d, u, s, t, h, e, r, e} {n, o, c, i, t, y, d, u, s, t, h, e, r, e) because

Determine whether the statement below is true or false. If ACB and dEB, then DEA Choose the correct answer below. O A. The statement is false. The correct statement is If ACB and dEA, then dEB. B. The statement is true.

Determine whether the statement below is true or false. If it is false, rewrite it as a true statement. The number of different ordered arrangements of n distinct objects is n!. Choose the correct answer below. O A. The statement is true. O B. The statement is false. A true statement is, "The number of different unordered arrangements of n distinct objects is n!." O C. The statement is false. A true statement is, "The number of different ordered arrangements of n distinct objects is n." O D. The statement is false. A true statement is, "The number of different ordered arrangements of n distinct objects is (n- 1)!."

Find the number of different types of full houses. (Ignoring suit.)

Let X={a,b,c,d}   Let T1={X, emptyset, {a}, {a,c}, {b}, {b,c}, {a,b},{a,b,c}, {b,c,d}} T2={X, emptyset, {b}, {b,d}, {c}, {c,d\}, {b,c},{b,c,d}, {a,b,c}}   how that the T1 and T2 topologies are topologically equivalent (you can give the homeomorphism or show that they are by their bases)
