Answer:
And we can find this probability using the complement rule and with the normal standard distribution or excel like this:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
For this case we have two resistors with the following distributions:
And for this case we want the following probability:
First we need to find the distributon for
Since both are normally distributed we have that a linear combination of normal distributions is also normal, so then we have this:
And we can use the z score formula given by:
And using this formula we got:
And we can find this probability using the complement rule and with the normal standard distribution or excel like this:
