B is correct.....

The x coordinates don't change

The y's just change signs.....

Correct, Synth....!!!!

See here, NSS :

https://www.mathsisfun.com/geometry/transformations.html

Reflection across  the x  axis does not change the x coordinate(s)

It just changes the sign of the y coordinate(s)

So....the original coordinates are

A =  ( 2, 5)      

B =  ( 6, 3)

Based on this, NSS, what would be  A'   and B'     ?????

Correct   !!!!

People confuse probability and odds

Probability   =   Favorable outcomes / Total Outcomes    =    2   /  7

Odds   =    Favorable outcomes / Unfavorable outcomes

Note, NSS....we have 2 favorable outcomes  to 7 total outcomes

So....we must have  7 - 2  =  5 unfavorable outcomes

So...the odds are

2 / 5   ⇒   D

Doet that make sense ???

Here's what this website calculates (in dollars....the pounds would be the same ) :

Good morning, shrek  !!!!

(Facepalm)......that was too easy, GA......

I should have consulted one of your learned  chimps.....even THEY could have done better than I did!!!!

GOOD JOB!!!!
