To ascertain the effectiveness of an advertising campaign for the Red Cross Annual Appeal on donations, a telephone survey of 676 Brisbane residents was conducted. Two of the questions asked were

1. Did you see the advertisement for the Annual Appeal? 2. Did you donate to the Appeal?

264 of the survey respondents indicated they saw the advertisement for the Annual Appeal. Of these 264 respondents, 26 of them indicated that they did not donate to the Annual Appeal. Overall, 275 respondents did not donate to the Appeal. One of the respondents from the survey was chosen at random. What is the probability that this respondent donated to the Annual Appeal or saw the Annual Appeal advertisement? (3 decimal places)
