Suppоse а cаmpus оrgаnizatiоn surveyed 200 freshmen and 300 sophomores about their preference of Raising Cane's vs. Layne's. 30% of freshmen said they preferred Layne's, 20% said they preferred Cain's, and 50% had no preference. Meanwhile, 25% of sophomores said they preferred Layne's, 30% said they preferred Cain's, and 45% had no preference. Every participant was entered into a drawing for a gift card. There was only one winner, and each participant was equally likely to be chosen. If the winner said they preferred Cain's in the survey, what is the probability that they were a sophomore?
