2030 randomly selected adults were asked if they think they are financially better off than their parents. The following table gives the two-way classification of the responses based on the education levels of the persons included in the survey and whether they are financially better off, the same, or worse off than their parents.

Better off	140	450	420
Same	60	280	110
Worse off	200	300	70

Suppose one adult is selected at random from these 2030 adults. Find the following probability.

Round the answer to three decimal places.
