A study investigates the effectiveness of a new flu vaccine. The one-year study enlists several thousand volunteers. 40% of the volunteers are diagnosed with flu during the course of the study, and 60% are not diagnosed with flu. Of the participants who are diagnosed with flu during the study, 20% had gotten the vaccine. Overall, 45% of participants had been assigned to the vaccine condition in the study. What proportion of participants did not contract flu and had gotten the vaccine? Show your work.
