The probability of picking a blue chip is the number of blue chips (5) divided by the total number of chips (10 red + 5 blue = 15). This gives 5/15, which corresponds to option D.

Explanation: There are a total of 10 red chips + 5 blue chips = 15 chips in the bag. The probability of picking a blue chip is the number of blue chips divided by the total number of chips, which is 5 blue chips out of 15 total chips. Therefore, the correct answer is D. 5 out of 15.

deepseekv3 To determine the probability of picking a blue chip, we use the formula:

\[
\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}
\]

In this case:
- The number of favorable outcomes (picking a blue chip) is **5**.
- The total number of possible outcomes (total chips in the bag) is **10 red chips + 5 blue chips = 15**.

So, the probability of picking a blue chip is:

\[
\frac{5}{15}
\]

Thus, the correct answer is **D. 5 out of 15**.
