To understand A subset B we will draw a figure

That means A is inside be

Then the intersection between A and B should happen in A

Since P(A) = 0.28

Since p(B) = 0.45

Then

$P(A\cap B)=P(A)=0.28$

To find A union B we will add A and B but since A is inside B, then we will not repeat it, then it should be B

$P(A\cup B)=P(B)=0.45$
