Sum or product

What is the probability that two dice fall will have the sum 7 or product 12?

Correct answer:

p =  0.2222

Step-by-step explanation:

$$\begin{gathered} X=(2+5,1+6,3+4,2.6) \\ t=6\cdot 6\mathrm{/}2=18 \\ p=4\mathrm{/}t=4\mathrm{/}18={\displaystyle \frac{2}{9}}=0.2222 \end{gathered}$$
