In this problem, we have been given some information about how many customers at a restaurant order an alcoholic drink and how many of them order an appetizer with dinner.
00:09
And we need to find the percentage of customers who order an alcoholic drink but do not order an appetizer.
00:15
So let's solve this problem using a venn diagram.
00:19
Consider this set over here.
00:22
Let's consider this to be the set d and this represents the event of ordering an alcoholic drink with dinner.
00:28
And let's consider this set over here.
00:31
Let us consider this to be the set a, and let this represent the event of a customer ordering an appetizer with dinner.
00:38
And let us consider this to be the universal set.
00:42
This represents all of the customers.
00:46
So let us consider the given information.
00:50
First of all, it is said that 35 % of customers order an alcoholic drink and an appetizer.
00:55
So we have 35 % over here in the intersection.
00:59
Of the few sets.
01:01
Then it is said that 10 % of customers do not order an alcoholic drink or an appetizer with dinner...
