Answer 1

To find the frequency of red flowers in the population, you need to use the formula for frequency, which is:

\[ \text{Frequency} = \frac{\text{Number of red flowers}}{\text{Total number of flowers}} \]

From the data provided:

• Blue flowers: 120
• Red flowers: 100
• Yellow flowers: 180

First, we calculate the total number of flowers:

\[ \text{Total flowers} = 120 + 100 + 180 = 400 \]

Now, we can calculate the frequency of red flowers:

\[ \text{Frequency of red flowers} = \frac{100}{400} = 0.25 \]

So, the frequency of red flowers in the population is 0.25.
