(a) Bird

(b) 40%

(c) 7%

Step-by-step explanation:

The pie chart is attached below.

Approximate the portion of each type of pet as follows:

Fish ≈ 15%

Bird ≈ 33%

Dog ≈ 17%

Cat ≈ 23%

Other ≈ 7%

None ≈ 5%

(a)

The pet category "Bird" was selected by approximately one-third of

the community.

(b)

The proportion of the community that chose Cat was, 23%.

The proportion of the community that chose Dog was, 17%.

So, the proportion of the community that chose Cat or Dog was:

Cat% + Dog% = 23% + 17%

                       = 40%

(c)

The proportion of the community that chose "Other" was approximately 7%.
