Hi,

In a recent survey 64% of the cars entering the Maine turnpike at Kittery had out of state plates, of which 75% were tourists.  

P(out of state) = 64/100 = 16/25



a)The car has Maine plates?

1- 16/25 = 9/25



b)It has out of state plates but still does not contain tourists?

16% or 16/100 = 4/25



c)It has out of state plates and tourists?

48% or 48/100 = 12/25
