Answer:
x >25
Step-by-step explanation:
Answer: C) 42
There are 7 ways for the first place winner to be chosen. Once that position is locked up, there are 6 ways to have someone picked for second place (since that first place runner can't simultaneously be in both places at once)
So we have 7*6 = 42 different permutations.
The longer way to get this answer is to use the permutation formula as shown below
nPr = (n!)/(n-r)!
7P2 = (7!)/(7-2)!
7P2 = (7*6*5!)/(5!)
7P2 = 7*6 <---- note how this shows up, as we found earlier
7P2 = 42
Either way, the answer is 42
