Answer #1

This is Binomial Probability Distribution with n = 20 & p = 20% = 0.20

c = 10

by using TI-84 calculator

The required probability will be ;

binomcdf(n=20,p=0.20,c=10)

the probability is 0.0020.

A manufacturer of semiconductors has a 20% defect rate in the semiconductors produced. Every hour, ten semiconductors are selected at random and inspected for defects. If more than three defectives in ten are observed, the process is stopped. If the probability a semiconductor is defective is not affected by whether the other semiconductors are defective, Question (A) Find the probability the manufacturing process must be stopped within the next hour. Question (B) What is the probability that the process will...
