Question 130
Nine balls of the same size and color, numbered $1, 2, \dots, 9$, were put into a packet. Now $A$ draws a ball from the packet, noted that it is of number $a$, and puts back it. Then $B$ also draws a ball from the packet and noted that it is of number $b$. Then the probability for the inequality $a - 2b + 10 \gt 0$ to hold is ( ).
