Answer: There are 76 animals seen by the veterinarian this week.
Step-by-step explanation:
Since we have given that
Number of dogs = 47
Number of cats = 19
Number of exotic birds = 7
Number of horses = 3
Total number of animals seen by the veterinarian this week is given by

Hence, there are 76 animals seen by the veterinarian this week.
There are 1679616 possible outcomes.
There are 6 possible outcomes for each roll; 6^8 = 1679616
Intuitively, one would think the ball would land in the green spot 2 out of the 38 times, since there are 38 slots and 2 are green.
The probability that it lands in a green section is 2/38. Multiplying this by the number of times the experiment is performed, we get (2/38)(38) = 2.
