Answer

Explanation:

Step1: Identify favorable outcomes

We need sum less than 7. Sum values are 2, 3, 4, 5, 6. Add their frequencies: $5 + 9+15 + 21+25=75$.

Step2: Calculate experimental probability

Experimental probability $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. Total number of experiments is 200. So $P=\frac{75}{200}=0.375$.

Answer:

$0.375$
