The following magazines are in a rack at a doctor's office. • 1 sports magazine
• 2 movie magazines
• 3 news magazines
• 3 science magazines

Gwen will choose a magazine at random, put it back, and choose another magazine. What is the probability that she will choose a science magazine and then a movie magazine?

A: 2/27
B: 1/12
C: 5/9
D: 7/12​

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
