How to find the average of distinct values from multiple columns - hive

Question

Below is a piece of input data from 200000 lines.
And I'm using the below command to find the average and expecting O/P like: M 50% F 50%
select avg(sum(case when col1='M' then 1 end)+
sum(case when col2='M' then 1 end)+
sum(case when col3='M' then 1 end)+
sum(case when col4='M' then 1 end)+
sum(case when col5='M' then 1 end)) as M,
avg(sum(case when col1='F' then 1 end)+
sum(case when col2='F' then 1 end)+
sum(case when col3='F' then 1 end)+
sum(case when col4='F' then 1 end)+
sum(case when col5='F' then 1 end)) as F
from household;
But shows an error:

Try this query in Hive. It would work just fine.
SELECT
y.M1/(y.M1 + y.F1) * 100 AS M,
y.F1/(y.M1 + y.F1) * 100 AS F
FROM (
SELECT
(x.SumMCol1 + x.SumMCol2 + x.SumMCol3 + x.SumMCol4 + x.SumMCol5) AS M1,
(x.SumFCol1 + x.SumFCol2 + x.SumFCol3 + x.SumFCol4 + x.SumFCol5) AS F1
FROM (
SELECT
SUM(IF(col1 = 'M', 1, 0)) AS SumMCol1,
SUM(IF(col2 = 'M', 1, 0)) AS SumMCol2,
SUM(IF(col3 = 'M', 1, 0)) AS SumMCol3,
SUM(IF(col4 = 'M', 1, 0)) AS SumMCol4,
SUM(IF(col5 = 'M', 1, 0)) AS SumMCol5,
SUM(IF(col1 = 'F', 1, 0)) AS SumFCol1,
SUM(IF(col2 = 'F', 1, 0)) AS SumFCol2,
SUM(IF(col3 = 'F', 1, 0)) AS SumFCol3,
SUM(IF(col4 = 'F', 1, 0)) AS SumFCol4,
SUM(IF(col5 = 'F', 1, 0)) AS SumFCol5,
COUNT(*) AS TotalRows
FROM
household
) x
) y;
