Mathematics - Probability Question with Solution | TestHub

In a $3\times 3$ matrix the entries $a_{ij}$ are randomly selected from the digits \{0,1,2 $\_\_\_\_$ 9\} with replacement. The probability that the numbers of the form xyz where $\mathrm{x},\mathrm{y},\mathrm{z}$ are the elements in each row will be divisible by 11 is $\frac{7^{K_1}.13^{K_2}}{10^9}$ then $K_1+K_2=$ $\_\_\_\_$
