Answer:
The probability they each indicate the same tire is 
Step-by-step explanation:
There will be 4 cases involved as there are 4 tires.
Probability of choosing front left tire is
as there are a total of 4 tires and we need to choose 1.
Now, if all the four students chose the front left tire then the probability is the product of individual probabilities.
Therefore, probability that all 4 students chooses front left tire is:

Similarly, the probabilities of choosing the remaining 3 tires by all the students would be:
,
, 
Therefore, the probability that they indicate the same tire is the sum of all these probabilities.
