I have created a column to calculate the outcome, let me know how the percentage should b calucated if you need help.

Outcome = 
VAR __userid = Table1[userld]
VAR __questionday = Table1[question Day]
VAR __T = CALCULATETABLE( VALUES( Table1[Answer]), Table1[userld] = __userid, Table1[question Day] = __questionday, REMOVEFILTERS() )
VAR __Y = "Yes"
VAR __N = "No"
VAR __NA = "n/a"
VAR __NotA = "not answered"
VAR __RESULT = 
    SWITCH(
        TRUE(),
        __Y in __T , __Y,
        NOT __Y in __T && __N IN __T ,  __N,
        COUNTROWS(__T) = 1 && __NotA IN __T , __NotA
    )
RETURN
    __RESULT
