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%)

Answer:

1/216

Step-by-step explanation:

multiply 1/6 by 1/6 by 1/6 essentially

(1/6)^3

1/216
