Determine if the scenario is independent or dependent:
"Assigning players positions on a sports team (in a way that everyone
gets a position and no one can have more than one)"

dependent

Step-by-step explanation:

A scenario is called independent if the outcome of one event will not influence the outcome of the other. We are trying to assign a position for each player so that everyone gets a position. But we also need to make no one can have more than one position.  

Let's say we have position X, Y, Z for player A, B, C. First you assign the position for player A, there will be 3 possible positions (A/B/C). If you assign position X to player A, player B can't get the X position so the possible outcome is only two(B or C). This makes the scenario dependent because the outcome of the first roll will influence the possible outcome of the next roll.

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!

you're missing vital information, add to it so we can solve this problem for you.
