Sum on dice

We have two dice. What is the greater likelihood of fall a total sum 7 or 8 ? (write 7, 8 or 0 if the probabilities are the same)?

Correct answer:

x =  7

Step-by-step explanation:

$$\begin{gathered} 7=1+6=2+5=3+4=4+3=5+2=6+1 \\ 8=2+6=3+5=4+4=5+3=6+2 \\ {p}_1>p_2 \\ x=7=7 \end{gathered}$$

7=1+6=2+5=3+4=4+3=5+2=6+1
8=2+6=3+5=4+4=5+3=6+2
p1>p2
x=7

hmmm, so we have 8 = 4+4 = 4+4 (thus one less variation than 7)
