A community group orders 1,250 water bottles to donate to the runners in a marathon. If the probability of a water bottle being defective is 1.2%, predict how many of the water bottles are likely to be defective. Round your answer to the nearest whole number.
a. 12
b. 15
c. 130
d. 150
Please help me
0.012 * 1250 = ?
15. Thanks (:
You're welcome.
Can I ask another?
Teesha is in French Club. There are 10 freshman, 12 sophomores, 15 juniors, and 30 seniors in the club. The advisor is going to randomly choose one of the members of the club to be a guide for an important visitor.
There's no question in that one.
The choices.
37/67
45/67
52/67
57/67
I think it is C.
Here is the question.
Find the probability that she will not choose a freshman.
There are 67 members in the club. There are 10 freshmen. The probability that a freshman IS chosen is 10/67. So, subtracting 10 from 67, you get 57.
The probability that a freshman IS NOT chosen is 57/67.
OMG! Thanks.
To predict how many of the water bottles are likely to be defective, we need to multiply the total number of water bottles by the probability of a single water bottle being defective.
Step 1: Calculate the number of defective water bottles.
The probability of a water bottle being defective is 1.2%. This can be written as 0.012 in decimal form.
Number of defective water bottles = 0.012 * 1,250
Step 2: Calculate the predicted number of defective water bottles.
Number of defective water bottles = 0.012 * 1,250 = 15
Rounding the answer to the nearest whole number, we find that approximately 15 of the water bottles are likely to be defective.
Therefore, the correct option is b. 15.
