Answer:
The required probability is 0.015625.
Step-by-step explanation:
Consider the provided information.
There number of tires are 4.
The number of workers are 4.
The probability that individual select front drivers side tire =
The probability that they all select front drivers side,tire is:
Similarly,
The probability that they all select front passenger side, tire is:
The probability that they all select rear driver side,tire is:
The probability that they all select rear passenger side, tire is:
Hence, the probability that all four workers select the same tire =
the probability that all four workers select the same tire =
Hence, the required probability is 0.015625.
