In the television program "Big Sisters," 12 candidates remain. The public chooses four candidates for the final round. Each candidate has an equal probability of being chosen. The Gotham Echo reckons that the local heroine, Stella Stone, has a probability of 38.5% of getting through to the final: they give her a 1/12 probability of being chosen first, a 1/11 probability of being chosen second, a 1/10 probability of being chosen third, and a 1 9 probability of being chosen fourth. Is this calculation correct?
