If only 3% of electric light globes manufactured by a company are defective, use an appropriate approximation to determine the probability that in a random sample of 100 globes manufactured by this company at least one globe is defective. State your answer to four decimal places.
A company operates an assembly line. The company believes that there is a 3% probability that any given item produced on the line will contain a defect. If 100 items are pulled at random from the line, what is the probability there will be exactly 4 defective items? If 100 items are pulled at random from the line, what is the probability there will be 9 or more defective items? If X = the number of defectives in a sample...

A box of 8 flashbulbs contains 3 defective bulbs. A random sample of 2 is selected and tested. Let X be the random variable associated with the number of defective bulbs in a sample. (A) Find the probability distribution of X. (B) Find the expected number of defective bulbs in a sample.
An individual is looking to purchase a 100 lightbulbs. They want to test 4 of these lightbulbs before buying the 100 lightbulbs. If a set of a 100 bulbs contains 10 defective bulbs, what is the probability that they will find no defective bulbs in a 4 bulb sample. Solve this using the binomial distribution and show your work.
