Question

is this equation true in probability. P(none) = 1- p ( atleast one)​

Answer 1

Answer:

No,

This is the correct one,

P(at least one) = 1 – P(none)

Explanation:

To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1. That is, P(at least one) = 1 – P(none). Top ford supplies X-Data DVDs in lots of 50, and they have a reported defect rate of 0.5% so the probability of a disk being defective is 0.005.
