A math problem about probability! 20 14 middle school Tanggu exam questions! Thank you~
The topic is unclear.

This topic is controversial: the key is to look at the gauge.

(1) If the order is from small to large: A23456789 10jqk, the probability is 8/ 13.

(2) If the order is from small to large: 23456789 10jqkA, the probability is 7/ 13.

(3) If the order is from small to large: 3456789 10jqkA2, the probability is 6/ 13.

Different rules in different places will lead to different results. Our rules here are in accordance with method (3).

But according to the arrangement of the pictures, it seems that A is the largest, which is 7/ 13.
