Question

Using the two-way table representing horses on a horse farm, find the probability that a randomly selected horse is in the barn.

Answer 1

To find the probability, you have to divide the number of horses in the barn by the total number of horses.

Number of horses in the barn = 13
Total number of horses = 39

Divide:

13 ÷ 39 = 0.33

0.33 = 33% 

Answer = 33%(3rd choice)

Hope this helped :)

Answer 2

To find the probability of selecting a horse in the barn, we need to know the total number of horses and the number in the barn.

To find the total, add the values in the "Total" row:

16 + 11 + 12 + 39 = 78

To find the number of horses in the barn, add the values in the "In the barn" row:

4 + 2 + 7 + 13 = 26

Now divide 26 by 78 to find the probability:

26/78 = 1/3 or about 33%

The answer is 33%
