I have data as in the link I attached.enter link description hereThe data will be checked by several operators. Each operator must check data as much as 50% of the total data of each operator randomly.If the number of data from the operator is 5 then the data must be checked all.And the data checked is marked with the remark "yes", on the contrary, the remark "no" (column C).
An example on column D.
I am still confused about how to make a formula or script.
