Sets T/F and Fillers

If A is any set, then  $A\subset A$  

• True

• False

If M = { 1, 2, 3, 4, 5, 6, 7, 8, 9 } and B = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }, then $B\not\subset M$  

• True

• False

The sets { 1, 2, 3, 4 } and { 3, 4, 5, 6 } are equal

• True

• False

 $Q\cup Z=Q$  , where Q is the set of rational numbers and Z is the set of integers.

• True

• False

Let sets R and T be defined as

R = { $x\in Z$ | x is divisible by 2 }

T = { $x\in Z$ | x is divisible by 6 }. Then,  $T\subset R$  

• True

• False

Given A = { 0, 1, 2 }, B = { x ∈ R | 0 $\le$  x $\le$  2}. Then, A = B

• True

• False

The set { x $\in$ R : 1 $\le$  x < 2  } can be written as

When A =  $\phi$  , then number of elements in P(A) is

If A and B are finite sets, such that $A\subset B$  , then n (A $\cup$ B) is equal to
