Developing a small driving range for golfers of all abilities has long been a desire of John Jenkins. John however believes that the chance of a successful driving range is only about 40%. A friend of John's has suggested that he conducts a survey in the community to get a better feeling of the demand for such a facility. There is a 0.9 probability that the research will be favourable if the driving range facility will be successful. Furthermore it is estimated that there is a 0.8 probability that the marketing research will be unfavorable if indeed the facility will be unsuccessful. John would like to determine the chances of a successful driving range given a favourable result from the marketing survey.
