Answer 1

To find the experimental probability of the seeds germinating, we can use the formula:

\[
\text{Experimental Probability} = \frac{\text{Number of successful outcomes}}{\text{Total number of trials}}
\]

In your case:
- Number of successful outcomes (germinated seeds) = 30
- Total number of trials (sown seeds) = 40

So, the experimental probability of a seed germinating is:

\[
\text{Experimental Probability} = \frac{30}{40} = \frac{3}{4}
\]

Next, to estimate the number of seeds that will germinate if you sow 20 seeds, we can multiply this probability by the number of seeds:

\[
\text{Estimated germinated seeds} = \text{Probability} \times \text{Number of seeds sown} = \frac{3}{4} \times 20 = 15
\]

Thus, the approximate number of seeds that will germinate if you sow 20 seeds is **15**.
