There are 10 women and 3 men in room a. one person is picked at random from room a and moved to room b, where there are already 3 women and 5 men. if a single person is then to be picked from room b, what is the probability that a woman will be picked

The probability that a woman will be picked from room B is 0.34.

Step-by-step explanation:

There are 13 persons in room A, which 10 are women. So, the probability that a woman gets picked to be transfer to room A is 10/13 = 0.77.

Then, in room B there will be a total of 9 persons, assuming that a woman got picked from room A, the probability of that a woman will be picked from room B is 9/4 = 0.44 x 0.77 = 0.34.

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'.
