Answer:
The fraction of species that are not venomous to the total number of snakes is 0.78
Step-by-step explanation:
Total number of species of snakes in the world = 2,700
Total number of venomous species of snakes in the world = 600
So subtracting the number of venomous species from number of species of snakes will give the number of non venomous species.
Hence,
[tex]\text{Number non venomous species}=2700-600=2100[/tex]
The fraction of species that are not venomous is,
[tex]=\dfrac{\text{Number non venomous species}}{\text{Total number of species}}[/tex]
Putting the values,
[tex]=\dfrac{2100}{2700}=0.7777....\approx 0.78[/tex]
