At a certain
a certain school it was found that 35% of the 500 boys and 40%
ioved bushwalking. One student from the school is chosen at rand
of the 500 boys and 40% of the 400 girls
resent the event that the student is a girl, and B represent the event
school is chosen at random. Let G
sa girl, and B represent the event that the student
enjoys bushwalking.
Find, correct to two decimal places:
i Pr(G)
ii Pr(BG)
iii Pr(B\G')
iv Pr(BNG)
v Pr(BNG')
b Find Pr(B).
c Hence find:
i Pr(
GB)
ii Pr(G|B')

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz

b is the answer that makes most sense

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'.

did you get the answer yet?
