I have a column in google spreadsheet name `domains` which contains the array of values like `['non work', 'work', 'work', 'non work']`, is there a way to find the count within that column which equals to `work` 

Below is the screenshot of what I want to achieve.

In `Work Domain Count` column values should be respectively 3, 2 and 0
