Answer:

The probability  that all the notes will be inserted into the correct envelopes is 1/6 or 0.166667.

Step-by-step explanation:

All the possible combinations are given by 3!=3x2x1=6. There are 6 possible ways in which the letters can be mailed. One of these ways is that the direction is correct. So the probability is 1/6=0.166667.
