In a survey of a community, it was found that 55% like summer season, 20% like winter season, 40%
don't like both seasons and 750 like both seasons. By
using Venn diagram, find the number of people who
like winter season.​

The number of people who like winter season is 1000.

Step-by-step explanation:

Event event correspond to a set in the Venn diagram, and we use it to find the percentages.

I am going to say that:

Event A: Like summer season

Event B: Like winter season.

55% like summer season

This means that

20% like winter season

This means that

40% don't like both seasons

This means that 100% - 40% = 60% like at least one, which means that

Proportion who like both:

This is . The measures are related by the following equation:

Using what we have

750 like both seasons.

This is 15% of the sample. So the total number of people is t, for which:

20% like winter season

Out of 5000. So

0.2*5000 = 1000

The number of people who like winter season is 1000.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
