Box1: 40 green balls, 3 red balls, 28 blue balls Box2: 22 green balls, 24 red balls, 30 blue balls Experiment: Randomly select one of the two boxes with a 75% of selecting box 1, and 25% chance of selecting box 2, and then draw two balls from the selected box. Record the box number as the r.v. i, and the colors of the two balls as b1, b2. Compute P( i = 1 | b1 = blue) [Round to...
