Suppose that 3 -you notes are written and 3 envelopes are addressed. accidentally, the notes are randomly inserted into the 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 0.17.

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.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
