An insurance company has a paper record and an electronic record for every claim. For an inaccurate paper record, 60% chances that the electronic record is inaccurate. For an inaccurate electronic record, 75% chances that the paper record is inaccurate. 3% of all the claims are inaccurate both in paper record and in electronic record. Pick one claim randomly, what are the chances that it is both accurate in paper record and in electronic record?
     A.97% B.94% C.68% D.65% E.35%

0.6inaccurate paper record=0.03，所以inaccurate paper record占全部的5%
0.75inaccurate electronic record=0.03，所以inaccurate electronic record, 4%
所以其中一个不正确，或者两者都不正确的有5+4-3=6，
所以都正确是1-6%=94%
