Supposed two air fryers are tested. Let D be the random variable representing the number of defecting air fryers that occur. Find the values of random variable D. Make a table showing the possible outcomes with its corresponding values for the random variable D.
Sample 3 cards are drawn without replacement from a population of five cards numbered 2 to 6
How many possible samples can be drawn?
List all the possible samples and compute the mean of each sample.
Construct the sampling distribution sample means.

1:The average amount of miles a car battery lasts for in a 2019 sedan is 37,452 miles with a standard deviation of
4,890 miles. If this distribution is normally distributed, answer the following questions:
A: What is the probability you select a battery it last longer than 40,000 miles?
B: What is the probability you select a battery, and it lasts between 32,000 miles and 44,000 miles?
C: Where does the top 18% of longest lasting batteries begin (at what mileage)?
Test whether the series ∞Σn=0 1/(n^5+x^3) converges uniformly or not
An electrical firm manufactures light bulbs that have a length of life that is approximately normally distributed, with mean equal to 813 hours and a standard deviation of 65 hours. Find the probability that a random samples of 34 bulbs will have an average life of greater than 803 hours.
