To find the experimental probability that a given bulb will have an error, you can use the formula for probability:
\[
P(\text{error}) = \frac{\text{Number of errors}}{\text{Total number of bulbs}}
\]
In this case, the number of bulbs with errors is 5, and the total number of bulbs is 25.
So, the experimental probability is:
\[
P(\text{error}) = \frac{5}{25} = \frac{1}{5} = 0.2
\]
Thus, the experimental probability that a given bulb will have an error is **0.2**.
\[
P(\text{error}) = \frac{\text{Number of errors}}{\text{Total number of bulbs}}
\]
In this case, the number of bulbs with errors is 5, and the total number of bulbs is 25.
So, the experimental probability is:
\[
P(\text{error}) = \frac{5}{25} = \frac{1}{5} = 0.2
\]
Thus, the experimental probability that a given bulb will have an error is **0.2**.
