Abox is filled with 7 red cards, 4 brown cards, and 3 yellow cards. a card is chosen at random from the box. what is the probability that it is a red or a yellow card? write your answer as a fraction in simplest form.

A - choosing a red or a yellow card

answer: i'm not sure

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
