A quality control inspector found flaws in 13 out of 150 sweaters. Find the probabillity that a sweater has a flaw. Round to nearest tenth of a %
Divide 13 by 150 (13/150) to get your percentage.
I hope this helps. Thanks for asking.
To find the probability that a sweater has a flaw, we can use the formula:
Probability = Number of favorable outcomes / Total number of possible outcomes.
In this case, the number of favorable outcomes is the number of sweaters with flaws, which is given as 13. The total number of possible outcomes is the total number of sweaters being considered, which is 150.
So, the probability of a sweater having a flaw is:
Probability = 13 / 150
Now, let's calculate this probability:
Probability = 0.0867
To round this to the nearest tenth of a percent, we multiply by 100:
Probability = 8.67%
Therefore, the probability that a sweater has a flaw is approximately 8.7%.
