-- 9 people paint 5 walls in 60 minutes
-- 9 people paint (5 / 5) = 1 wall in (60 / 5) = 12 minutes
-- (9 / 9) = 1 person paints 1 wall in (9 x 12) = 108 minutes
-- 1 person paints (1 x 6) = 6 walls in (108 x 6) = 648 minutes
-- (1 x 4) = 4 people paint 6 walls in (648 / 4) = 162 minutes .

Answer:
0.2
Step-by-step explanation:
Given the data :
Day : Mon Tue Wed Thu Fri Sat Sun
# of sick days 22 11 16 17 21 28 25
The expected count of sick days taken on Saturday is obtained thus :
Expected count = (row total * column total) / overall total
Here, the table is just one way :
Hence, we use :
Observed value / total days
Hence,
Expected count on Saturday = sick days on Saturday / total sick days
Expected count on Saturday = 28 / (22+11+16+17+21+28+25)
Expected count on Saturday = 28 / 140
= 0.2
