The table shows the drink preferences of 50 shoppers at the mall. What is the probability that one shopper, selected at random from the 50 surveyed, preferred either Drink B or Drink A?
You can't show the table here.
Drink B is 8 people and drink A in 7 people.
To find the probability that a random shopper preferred either Drink B or Drink A, we need to determine the number of shoppers who preferred either Drink B or Drink A and divide it by the total number of shoppers surveyed.
Without the exact numbers, it is impossible to provide an exact probability. However, if you have the numbers, follow these steps:
1. Count the number of shoppers who preferred Drink B.
2. Count the number of shoppers who preferred Drink A.
3. Add the number of shoppers who preferred Drink B and Drink A (assuming they are mutually exclusive).
4. Divide the sum by the total number of shoppers surveyed (50 in this case).
5. Multiply the result by 100 to get the probability as a percentage.
Here is the formula:
P(Drink B or Drink A) = (Number of shoppers who preferred Drink B + Number of shoppers who preferred Drink A) / Total number of shoppers surveyed
For example, if 10 shoppers preferred Drink B and 15 shoppers preferred Drink A:
P(Drink B or Drink A) = (10 + 15) / 50
P(Drink B or Drink A) = 25 / 50
P(Drink B or Drink A) = 0.5
So, the probability is 0.5 or 50%.
To find the probability that a shopper preferred either Drink B or Drink A, we need to determine the number of shoppers who preferred either of those drinks and divide it by the total number of shoppers surveyed.
The information provided is that there are 50 shoppers surveyed, but we don't have the breakdown of how many preferred each drink. To find the answer, we need more specific data about the preferences of the shoppers.
If you have the data on how many shoppers preferred each drink, please provide those details so we can calculate the probability for you.
