How can I do this,and I want to know the DAX function for it? 

Answer 1

Use the following measures to acheive that

AVG AM = AVERAGE('Table'[SalesAM])

Measure = CALCULATE(SUMX(SUMMARIZE('Table', 'Table'[product], 'Table'[State],"avg",[AVG AM]), [avg]), ALLEXCEPT('Table', 'Table'[Year], 'Table'[Product])) 

SUMMARIZE('Table', 'Table'[product], 'Table'[State],"avg", [AVG AM], [avg]) 

CALCULATE(SUMX(SUMMARIZE('Table', 'Table'[product], 'Table'[State], "avg", AVERAGE('Table'[SalesAM])), [avg]), ALLEXCEPT('Table', 'Table'[Year], 'Table'[Product]))
