Walnuts (also known as walnuts, almonds, cashews, and hazelnuts) are collectively known as the "four major dried fruits" in the world. They are widely planted, but the quality of walnuts varies due to different regions. It is known that two places, A and B, are major producers of walnuts. The empty shell rate of walnuts planted in place A is 2% (the empty shell rate refers to the solidness index of nuts, grains, etc., where the flower is not fertilized, and the shell is completely empty), and the empty shell rate of walnuts planted in place B is 4%. If the walnuts planted in both places are mixed together, and it is known that the number of walnuts from places A and B accounts for 40% and 60% of the total respectively, then the probability of randomly selecting a walnut that is an empty shell is ______.
