An auto dealership wants to know the average amount of money its customers can spend on a car. The dealership surveys 50 random
customers and finds that 25 shoppers can spend $10,000 or less, 15 can spend $10,001 to $25,000, and 10 can spend more than $25,000. If 1000 customers visit the dealership this coming weekend, the dealership can estimate that _____ of its customers will have a budget greater than $25,000. Enter your answer as a number, like this: 42
Given:The dealership surveys 50 random customers and finds that 25 shoppers can spend $10,000 or less, 15 can spend $10,001 to $25,000, and 10 can spend more than $25,000.
To Find: If 1000 customers visit the dealership this coming weekend, the number of customers having budget greater than $25000.
Solution:
Total Number of surveyed customers=
The Number of customers that can spend =
The Number of customers that can spend to =
The Number of customers that can spend more than =
Percentage of people that can spend more than = Number of customers that can spend more than Total Surveyed Customers
=%
If customers visits the dealership,
customer that have budget greater than [= total visiting customers percentage of people that can spend more than
Hence the customers that having budget greater than will be
This problem is all about probability. It is the study of predicting the likelihood or chances of a certain event to happen out of all the possibilities. It is always expressed as a part of a whole. Therefore, the answer is either in fraction or in percentage.
A standard deck of card consists of 52 cards all in all. There are 13 diamond cards within the deck. So, the probability of getting a diamond card is 1/52. But we are given with a conditional probability. The first draw is sure to pick a diamond. So, the probability for this is 1 or 100%. But we should multiply this to the second scenario which is the 2nd draw. If you picked a card already, that means the total number of cards is 52 less 1. Also, because you already picked a diamond in the first draw, the diamond cards left in the deck is 13 less 1. Therefore, the probability of getting a diamond card in the second draw is
