Blood groups and types: If one person is selected, find the probability of getting someone who is group A or group B or type Rh−.

A) ( P({Group A}) + P({Group B}) + P({Type Rh−}) )
B) ( P({Group A} ∩ {Group B} ∩ {Type Rh−}) )
C) ( P({Group A} ∪ {Group B} ∪ {Type Rh−}) )
D) ( P({Group A} × {Group B} × {Type Rh−}) )
