Question 1152785: A manufacturing company regularly conducts quality control checks at specified periods on the products it manufactures. Historically, the failure rate for LED light bulbs that the company manufactures is 8%. Suppose a random sample of 10 LED light bulbs is selected. Complete parts (a) through (d) below.
a. What is the probability that none of the LED light bulbs are defective?

This is a binomial problem. Each selection is independent of one another, and a bulb is either defective or it is not defective.
p = 0.08 is the probability of being defective
1-p = 1-0.08 = 0.92 is the probability of not being defective
n = 10 is the sample size
Use the Binomial PDF function
x is a non-negative whole number representing the number of defective bulbs
Plug in n = 10 and p = 0.08
Now plug in x = 0, which will help us find the probability of x = 0 bulbs being defective
Use your calculator. This value is approximate.
When rounded to 3 decimal places, the approximate answer is 0.434
