write down the subsets set of P {0,phi,{phi}}

Write down all the possible proper subsets for each of the following. 1 {a, b, c, d} 2 {x} 3 φ 4 {5, 10}

If A is {{Φ}, {Φ, {Φ}}}, then the power set of A has how many element? a. 4 b. 2 c. 6 d. 8

How many elements has P (A), if A = Φ?

Text from your selection A ⊂ B (ii) A – B = Φ
