$\:\sf\underline\green{Given}\:$

• The annual rainfall in vindarbha in 5 yrs is given below.

• 900 mm, 650 mm, 450 mm, 733 mm, 400 mm.

$\:\sf\underline\orange{To\:find}\:$

• What is the average rainfall for those 5 yrs ?

$\:\sf\underline\blue{Formula\:used}\:$

• $\sf\:Average\:=\:\dfrac{Sum\:of\:all\: observations}{Total\: number\:of\:observations}$

$\:\sf\underline\pink{Solution}\:$

The observations are :

• 900 mm,
• 650 mm,
• 450 mm,
• 733 mm,
• 400 mm.

Total number of observations = 5

• $\sf\:Average\:=\:\dfrac{Sum\:of\:all\: observations}{Total\: number\:of\:observations}$

• $\sf\:Average\:=\:\dfrac{900\:+\:650\:+\:450\:+\:733\:+\:400}{5}$

• Average rainfall for those years = 626.6 cm
