Explanation:

Question 16

Step1: Count total photographs

Count the number of rows in the table. There are 10 rows (Lizard, Snake, Crocodile, Ostrich, Baboon, Lion, Zebra, Giraffe, Elephant, Cheetah). So total = 10.

Step2: Count mammal photographs

Count the number of rows where Type is Mammal. Baboon, Lion, Zebra, Giraffe, Elephant, Cheetah: that's 6.

Step3: Calculate the portion

Divide the number of mammal photographs by total. So $\frac{6}{10} = 0.6$.

Step1: Count total photographs

Total number of photographs is 10 (from Question 16).

Step2: Count non - mammal photographs

Non - mammal: Lizard, Snake, Crocodile (Reptiles: 3) and Ostrich (Bird: 1). So 3 + 1 = 4.

Step3: Calculate the portion

Divide non - mammal count by total. $\frac{4}{10}=0.4$.

Answer:

0.6
