Question

find the probability that at least 5 defective bolts will be found in a box of 200 bolts. If it is known that 2% are expected to be defective .
e^-4=0.0183​

Answer 1

Answer:

Hi there.. Here's the answer for your question..

Step-by-step explanation:

Here's one way to do this problem.

Poisson distribution (m = mean):

P(x) = e^(-m) m^x / x!

Note: mean = .02*200 = 4

Find P(0) through P(5). Add together for the probability.

Here's P(0):

P(0) = (e^ -4) (4^0) / (0!)

= (0.0183) (1) / (1)

= 0.0183

I hope this will help get you started.

If any doubt ask me..

Thank you..
