could someone please explain this in details?

Chebyshev Inequality A new product design is thought to decrease failure rates in production. The the success rate p is not known but the variance p[1-p) can be shown to be less than 0.05. Tests were conducted using 2500 samples. with a good part assigned the value of 1, and a failed part is assigned to O. In that test the success rate would be p, which we hope is within 0.01 of being accurate. The probability our hope is incorrect is P[|M25m p| 2 0.01} 3 (choose one): 0 1x20 0 1x100 0 H2500 0 1:5
