To find the probability that a unit will pass inspection, we can use the following formula:
\[
\text{Probability of passing} = 1 - \text{Probability of failing}
\]
First, we need to determine the number of units that passed inspection. Since 1,000 units were inspected and 120 units were rejected, the number of units that passed is:
\[
1,000 - 120 = 880
\]
Now we can calculate the probability of passing inspection:
\[
\text{Probability of passing} = \frac{\text{Number of units that passed}}{\text{Total number of units}} = \frac{880}{1,000} = 0.88
\]
So, the probability that a unit will pass inspection is:
\[
\boxed{0.88}
\]
\[
\text{Probability of passing} = 1 - \text{Probability of failing}
