Answer 1

Total number of students surveyed: 30

Number of students choosing a turtle: 4
Probability of choosing a turtle: 4/30 = 0.1333 or 13% (rounded)

Number of students choosing a gerbil or a snake: 6 (3 choosing gerbil and 3 choosing snake)
Probability of choosing a gerbil or a snake: 6/30 = 0.2 or 20%

Theoretical probability of selecting a cat is = the experimental probability of selecting a cat.
