Question

A box contains 6 nuts, 8 bolts, and 4 screws. If 3 objects are selected in succession randomly, what is the probability of selecting a nut, then a bolt, then a screw, if replacement occurs each time?

Answer 1

8/243

Explanation:

6+8+4=18

18 objects in total

6/18*8/18*4/18=1/3*4/9*2/9=8/243
