Nthe waiting room of a vet's office, there are 4 cats, 5 dogs, 1 lizard, and 1 hamster. a represents the event that a randomly selected animal in this waiting room is a dog. what is the probability of the complement of event a? enter your answer as a fraction, in simplified form, in the box

The probability is:

There are 4 cats, 5 dogs, 1 lizard, and 1 hamster.

A represents the event that a randomly selected animal in this waiting room is a dog.

This means that the probability of A is the ratio of number of dogs to the total number of animals.

i.e.

( Since the total number of animals are: 11

and the total number of dogs=5 )

Also, the probability of complement of A is given by:

Hence,

            Hence, the answer is:

3; 9 is 8 to -4

step-by-step explanation:

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
