7/11

Step-by-step explanation:

In this question case, we have 55 horses trained by the house farm, in the experiment, 35 horses were selected randomly. Now, we want to know the chances that these horses have.

Firstly, we must identify with that fact that the total number of horses or total number of sample is 55 horses.

Now, we are selecting 35 out of the house in the areas and we need to know the chances or the probability that these selected horses have.

Mathematically, to do this, we usually place the numbers of selected horses over the total number of horses and we make our division.

This means that we P = 35/55 = 7/11

The probability that each horse have for being selected is 7/111
