The probability under the question is

    %2820%2F%2812%2B20%29%29%2A%2812%2F31%29 = %2820%2F32%29%2A%2812%2F31%29.


This formula is self-explanatory.  If you have questions,  look into the formula attentively,  and then it will tell you everything about itself.

So,  my explanations are not required.


To get the number,  use your calculator.
