**Reiny**, Wednesday, April 15, 2009 at 11:06amperhaps I am missing something but

wouldn't the smallest percentage possible of people agreeing with both statements be 0% ?

and the largest percentage possible agreeing with both parts be 54% ?

**Sabrina**, Wednesday, April 15, 2009 at 11:11amThe 54% is correct but it says the smallest percent is incorrect

**Reiny**, Wednesday, April 15, 2009 at 11:23amtry this:

n(A or B) = n(A) + n(B) - n(A and B)

= .87 + .54 - n(A and B)

= 1.41 - n(A and B)

since we can't go over 100%

the n(A and B) must be .41 or 41% ????

(2011) 3,000 3,500 4,000 4,500

(2012) 2,000 2,334 2,667 3,000
