Don,Eric, and Finn line up in random order for the cafeteria line. What is the probability that they will line up from front to

Vanyuwa [196]

Answer:

1/6

Step-by-step explanation:

The number of ways they can line up is 3×2×1 = 6. Only one of these is alphabetical order. The probability that they will line up randomly in alphabetical order is 1/6.

Any of the three can line up first; either of the remaining two can line up second, and the remaining person can line up last. Thus there are 3×2×1 possible orders.
