Answer :
Probability
The probability of an event can be calculated with the formula:
[tex]\displaystyle P=\frac{f}{n}[/tex]Where f is the number of favorable cases and n is the total number of cases.
We are required to find the probability for Delta (a dog, for sure) of selecting a stuffed animal out of her basket.
There are f=9 stuffed animals out of a total of n=20 toys to chew, thus the required probability is:
[tex]\displaystyle P=\frac{9}{20}=0.45[/tex]The probability is 0.45 or 45%
