There are six beads of different colors, so the probability of picking any color is 1/6. Since she places the beads back in, each pick for a specific colors is still 1/6. She does this three times in a row so the probability of picking 3 different colors in three picks is:

(1/6) ^3

(1/6) (1/6) (1/6)

1/216 (0.463%)
