9 possible outcomes.
1. There are two coins being flipped.
Possibilities:
HH (two heads) HT (heads and tails) TT (two tails)
There are three sides to the spinner
Possibilities:
Side 1     Side 2    Side 3
Since there are 3 possibilities for each, multiply them together
So, 3*3 which equals 9 possibilities
        
                    
             
        
        
        
Answer:
The correct answer is option d)"the percentage of pink flowers should increase over time".
Explanation:
In this study it is stated that two factors affect the flower coloration of <em>Claytonia virginica</em>: slugs preference of eating pink-flowering plants and bees preference of pollinating pink-flowering plants as well. If the researcher removes all slugs from the study population we can expect that the percentage of pink flowers should increase over time. The removal of the predator that prefers eating pink-flowering plants will favor the reproduction of this type of plants, which are also favored by bees pollination preference.
