Freshman Sophomore Junior Senior STEM 89 28 52 58 Non-STEM 53 13 39 85 Suppose one student is randomly selected from the group. Calculate the following probabilities. Round solutions to three decimal places, if necessary. P(STEM) = P(Sophomore) P(Sophomore | Non-STEM) P(Sophmore and Non-STEM) Are the events "Sophomore" and "Non-STEM" indpendent or dependent? |Select an answer v P(Sophmore or Non-STEM) Check All Parts 72OF Q Search Partly cloudy
