A box contains 10 labeled pieces of paper. Each piece of paper has one integer ranging between 1 and 10 written on it, and the numbers are not repeated. If you draw a piece of paper at random, then the probability that the number is greater than 3 and less than or equal to 7 is closest to: A.0.5
B.0.4
C.0.6
