1 answer:
The sample of 800 consumers, 230 took coffee, 245 took tea and 325 took cocoa are shown in the picture by the Venn diagram.
<h3>What is the Venn diagram?</h3>It is defined as the diagram that shows a logical relation between sets.
The Venn diagram consists of circles to show the logical relation.
We have:
From a sample of 800 consumers, 230 took coffee, 245 took tea and 325 took cocoa, 30 took all the three beverages, 70 took coffee and cocoa, 110 took coffee only, and 185 took cocoon only.
We can represent the above data by the Venn diagram as shown in the picture.
From the Venn diagram:
The number of customers who took none of the beverages
= 800 - 580 = 220
The number of customers who took tea only = 95
The number of customers who took tea and cocoa only = 70
The number of customers who took tea and coffee only = 50
The number of customers who took none of the beverages = 220
Thus, in the sample of 800 consumers, 230 took coffee, 245 took tea and 325 took cocoa are shown in the picture by the Venn diagram.
