Expression: percentage

[#1]

Good evening. please I am a beginner with Qlik, and I have a problem with writing expressions.

I wanted an expression that would allow me to display in my dashboard the percentage of finalists who are second tasters.

here are my data. Please help me THANKS.

What defines first and second tasters? What is the expected output?

Thank you very much for having read my message .

The first taster is the one who starts the shoot-penalties in football and the second shooter comes after.

The finalists are those who lost the game. So I want the percentage of finalists who started the penalties in second place (deuxieme_tireurs) on one step, and the another side finalist who started penalties in first position (premier_tireurs)

The sector must display two finalist percentage(first taster and second taster)

Please sir  have you open my dashbord?

A first expression must therefore select each finalist(finaliste) who is first taster(premier_tireurs) and count them and calculate their percentage.

What is the expected output in numerical terms?

I expect two percentage values in the same sector. a percentage for the finalists who are first taster(premier_tireurs) and on the other hand a percentage of the finalists who are the second_taster(deuxieme_tireurs).
