To find the frequency of red flowers in the population, we need to calculate the total number of flowers and then determine the proportion of red flowers.
First, let's sum the total number of flowers:
- Blue flowers: 120
- Red flowers: 100
- Yellow flowers: 180
Total number of flowers = 120 + 100 + 180 = 400
Next, we calculate the frequency of the red flowers:
Frequency of red flowers = (Number of red flowers) / (Total number of flowers) Frequency of red flowers = 100 / 400 = 0.25
Thus, the frequency of red flowers in the population is 0.25.
