Hope it helps :D
This is the answer that i was going to upload :
the answer is +5(or)-5 because of root
In a throw of 2 fair dice, there are 6*6=36 equiprobability outcomes.
To get a sum of 5, there are 4 ways, (1,4),(2,3),(3,2),(4,1) with probability of 4/36=1/9
To get at least one 5, there are 6+6-1=11 outcomes (note (5,5) has been counted in both, so subtracted from sum). The probability is 11/36
Since the two events are mutually exclusive (once we have a five, the sum can no longer be 5), we can add the probabilities to get the probability of one event or the other.
P(sum of 5 OR at least one 5)=1/9+11/36=4/36+11/36=15/36=5/9

Answer:
B
Step-by-step explanation:
If we reorder the equation in a certain way then it will look like this:
y-4=1/2(x-6)
y-4=1/2x-3
y-1=1/2x
y=1/2x+1
therefore B is correct since we reduced the equation to y=1/2x+1.
It may be hard to understand but the question is basically asking which one of these answers is equal to y.
Hope this helped you and let me know if i messed up or if im correct so i can imporve from my mistakes
