Answer:
<em>4 white horses.</em>
Step-by-step explanation:
First, you need to find the total of the first set of horses (basically how many total were in the table).
<em>~ 3+2+9+1 = 15</em>
Next we need to find how many horses were white horses out of these 15 horses. In short the proportion would be White Horses/Total Horses.
<em>~ </em><em> (or </em>
<em>, simplified)</em>
Now, all we need to do is create the proportion with 20 as the denominator (in this case, 20 will be the total horses, and we just need to find <em>X</em>, or how many horses are expected to be white out of all of those horses). The proportion will look somewhat like this:
~ =
The final step is to multiply across (1x20) then divide that number by the 5 to find <em>X</em>.
<em>~ 20÷5 = 4</em>
Anyways, that means it would be expected to have <em>4</em> white horses out of 20 total. Hope this helped ^-^
