Answer:
The probability of spinning red is , the probability of spinning a 1 is
, the probability of spinning an odd number is
, and the probability of spinning a 9 is 0.
Step-by-step explanation:
Since there are a total of 6 possible outcomes, you can use this in the following questions. There are 2 red tiles, so the probability of spinning red is or
. Since there are only one 1 tile, the probability of spinning a 1 is
. Since there are three odd numbers, the probability of spinning an odd number is
. Since there are no 9 in the spinner, the probability of spinning a 9 is 0 or never.
Answer:
A guarantee of 6.24 years should be offered.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
If she is willing to replace only 3% of the motors that fail, how long a guarantee should be offered?
The 3rd percentile, that is, the value of X when Z has a pvalue of 0.03. So X when Z = -1.88.
A guarantee of 6.24 years should be offered.
