Question

The prediction of Weather in the month of September is given below.

(i) Make a frequency table of the types of weather by reading the calendar.
(ii) How many days are either cloudy or partly cloudy?
(iii) How many days do not have rain? Give two ways to find the answer?
(iv) Find the ratio of the number of Sunny days to Rainy days

Answer 1

(i) 

Type of weather	Tally mark	Frequency
Sunny	|||| ||||	10
Partly cloudly	|||| |	6
Cloudly	|||| |||	8
Rainly	|||| |	6
	Total	30

(ii) 14 days.

(iii) For 24 days there is no rain.

(a) From the total 30 days, we subtract the rainy days i.e 30 – 6 = 24 days ...(From the frequency table)

(b) From the picture, we can count the non-rainy days.

(iv) Ratio of number of Sunny day to Rainy days

= `"Number of Sunny days"/"Number of Rainy days"`

= `10 / 6`

 = `5/3`

= 5 : 3

The ratio of a number of Sunny days to Rainy days = 5 : 3
