Describing Events as Subsets of a Sample Space Using Characteristics of Outcomes

Given the sets: S = { 1, 2, 3, 4, 5, 6 } A = { 1, 2, 3 } B = { 2, 4, 6 } Which is correct?

Answer explanation

The symbol "⊃" is "superset"

"Superset" means the first set contains everything in the second set, but also other elements as well. For example:

{ 1, 2, 3 } ⊃ { 1, 2 }

For the symbol "⊂" means "subset".

"Subset" means that the first set contains some, but not all the elements of the second set, and that every element in the first set is also in the second set. For example:

{ 1, 2 } ⊂ { 1, 2, 3 }

Notice that, just like greater than, ">", and less than, "<", superset and subset are opposites. So if:

S ⊃ A

is true, then

A ⊂ S

is also true.

• intersection, "and"

• intersection, "or"

• union, "and"
