Probabilities are used to determine the chances of events
The probability of choosing a cat or dog is 1/2
The distribution of the animals is given as:
Dogs = 9
Cats = 6
Gerbils = 8
Parrots = 7
The number of cats or dogs is:
Cats or dogs = 6 + 9
Evaluate the sum
Cats or dogs = 15
There are 30 animals.
So, the probability that a selected animal is cat or dog is:
p = 15/30
Simplify
p = 1/2
Hence, the probability of choosing a cat or dog is 1/2
