Suppose A and B are sets. Select all true statements below. Select one or more: 1) If 2∈A∪B and 2∉A then 2∈B 2) If {2}∈A and {3}∈A then {2,3}⊆A 3) If {2,3}⊆A then 2∈A and 3∈A 4) If P(A)⊆B then...

1) If  2∈A∪B    and  2∉A    then   2∈B

2) If  {2}∈A  and  {3}∈A   then  {2,3}⊆A

3) If  {2,3}⊆A   then  2∈A   and  3∈A

4) If  P(A)⊆B   then  2|A|≤|B|

5) {2,3}⊆A∩B  implies that  {2,3}⊆A  and  {2,3}⊆B

Which options are correct?
