The table shows the drink preferences of 50 at the mall. What is the probability that one shopper,selected at ran from the 50 surveyed,preferred either drink A or drink B
Drink Survey
Drink : Number of shoppers
A : 7
B : 8
C :10
D :11
E :14
8/25
3/10***
11/25
7/25
Thank you again!
#1, ok
#2, I count 4 R's out of 8, so .... what is 4/8 = ?
#3 ok
1. The correct answer is 1/2. There are 2 numbers greater than 3 on a standard number cube, which are 4 and 5. Since there are a total of 6 possible outcomes (numbers 1 to 6), the probability of getting a number greater than 3 is 2/6, which simplifies to 1/3. However, the question asks for the probability of getting a number greater than 3, so the answer is 1 - 1/3 = 2/3.
2. The correct answer is 1/4. There are a total of 8 sections on the spinner, and only 1 of them is labeled with an "R". Therefore, the probability of the pointer landing on "R" is 1 out of 8, which simplifies to 1/8.
3. The correct answer is 11/25. The question asks for the probability that a randomly selected shopper preferred either drink A or drink B. From the given data, we can see that the number of shoppers who preferred drink A is 7, and the number of shoppers who preferred drink B is 8. So, the total number of shoppers who preferred either drink A or drink B is 7 + 8 = 15. Therefore, the probability is 15 out of 50, which simplifies to 15/50, or 3/10.
1. To find the probability of getting a number greater than 3 when tossing a standard number cube, you need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
Favorable outcomes: The numbers greater than 3 on a standard number cube are 4, 5, and 6. So, there are 3 favorable outcomes.
Total possible outcomes: A standard number cube has 6 sides, numbered 1 to 6. Therefore, there are 6 possible outcomes.
Probability = Favorable outcomes / Total possible outcomes
= 3 / 6
= 1/2
Therefore, the correct answer is 1/2.
2. To find the probability of the pointer landing on R when spinning the given spinner, you need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
Favorable outcomes: The spinner has 4 "R" sections out of a total of 8 sections. So, there are 4 favorable outcomes.
Total possible outcomes: There are 8 total sections on the spinner.
Probability = Favorable outcomes / Total possible outcomes
= 4 / 8
= 1/2
Therefore, the correct answer is 1/2.
3. To find the probability of a shopper, selected at random from the 50 surveyed, preferring either drink A or drink B, you need to determine the number of shoppers who preferred either drink A or drink B and divide it by the total number of shoppers surveyed.
Number of shoppers preferring drink A = 7
Number of shoppers preferring drink B = 8
Total number of shoppers = sum of all drink preferences = 7 + 8 + 10 + 11 + 14 = 50
Number of shoppers preferring drink A or B = 7 + 8 = 15
Probability = Number of shoppers preferring drink A or B / Total number of shoppers
= 15 / 50
= 3/10
Therefore, the correct answer is 3/10.
You answered all the questions correctly. Congratulations!
