Question

Farm animals in Slope County have a 5.5% chance of contracting a livestock disease. On Granny's ranch. 3 cows. 4 pigs.
and 2 chickens have caught the disease Granny has 53 cows, 75 pigs, and 30 chickens. Which of her types of animals
have stayed healthier than the county average?

Answer 1

Answer:  Pigs

Explanation:

For each animal type, divide the number who caught the disease over the total number of that particular animal.

• Cows: 3/53 = 0.057 = 5.7% approximately
• Pigs: 4/75 = 0.53 = 5.3% approximately
• Chickens: 2/30 = 0.067 = 6.7% approximately

Unfortunately the cows and chickens have percentages higher than 5.5%, so they are not healthier compared to the average.

Pigs on the other hand have a percentage less than 5.5%, so they seem to be slightly healthier than the county average.
