  • Randomly Selected Replacement for Drawing Balls

    Therefore, probability of drawing a ball with number greater than or equal to 17 = 4/20 = 1/5 Since three balls are drawn with replacement, probability that we win the bet =BINOMDIST(1,3,1/5,0) + BINOMDIST(2,3,1/5,0) + BINOMDIST(3,3,1/5,0) = 0.384
