In our virtual world, we own a construction company and bid on projects. Based on our past history of winning bids on projects, the probability of winning the next contract to build a school is 0.40, to build a hospital is 0.30 and to build both a school and a hospital is 0.20. What is the probability of winning a contract to build either the school or the hospital? The school only? The hospital only?© BrainMass Inc. brainmass.com October 10, 2019, 7:32 am ad1c9bdddf
We need use the Rule of Addition.
So P(build either the school or the hospital)=P(build the ...
The solution gives detailed steps on computing the probability using the Rule of Addition.
