Answer:
[tex]\frac{1}{210}[/tex]
Step-by-step explanation:
We can use the probability that one person will be assigned to one place.
For the first place in line, what is the probability that Moe will stand there?
[tex]\frac{1}{7}[/tex] because there is 7 people and 1 of Moe.
Then, for the second place in line, what is the probability that Larry will stand there?
[tex]\frac{1}{6}[/tex] because there are 6 people now and one of Larry.
Finally, for the third place in line, what is the probability that Curly will stand there?
[tex]\frac{1}{5}[/tex] because there are 5 people now and one of Curly.
To find the probability that they'll stand in that order, we can multiply the probabilities together.
[tex]\frac{1}{7}*\frac{1}{6}*\frac{1}{5}=\frac{1}{210}[/tex]
