explain why
The empirical probability of a unit passing inspection can be calculated by taking the number of units that passed inspection (1,000 - 150 = 850) and dividing it by the total number of units inspected (1,000).
So, the empirical probability that a unit will pass inspection is 850/1000 = 17/20. This simplifies to the fraction 17/20.
