A horse farm trained 55 horses. In a random selection process, 35 horses were chosen for the welcome parade. What chance did each horse have of being selected for the parade?

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

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

answer: ouch. thats difficult
