You sow 40 sunflower seeds, and 30 of them are germinated. Use experimental probability to approximate the number of seeds that will germinate if you sow 20 seeds? (1 point) 15 30 40 3/4

Answer 1

To find the experimental probability that a seed germinates, you can use the formula:

\[ \text{Probability of germination} = \frac{\text{Number of seeds that germinated}}{\text{Total number of seeds sown}} \]

In your case, you have:

• Number of seeds that germinated = 30
• Total number of seeds sown = 40

So the probability of germination is:

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

Now, if you sow 20 seeds, you can use this probability to predict how many of those seeds will germinate:

\[ \text{Expected number of seeds that will germinate} = \text{Probability of germination} \times \text{Number of seeds sown} \]

Calculating that:

\[ \text{Expected number of seeds that will germinate} = \frac{3}{4} \times 20 = 15 \]

So, if you sow 20 seeds, you can expect approximately 15 seeds to germinate. Therefore, the answer is 15.
