Suppose that 3 thank-you notes are written and 3 envelopes are addressed. Accidentally, the notes are randomly inserted into t
he envelopes and mailed without checking the addresses. What is the probability that all the notes will be inserted into the correct envelopes? The probability is 0.166667.
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.
