Question

if customers arrive at the banks drive up window at the rate of three per minute Works well with multiple outcomes as dichotomous outcomes e Constant probability O Trials are independent QUE STION 2 10 points If you are pulling a sample from a continuous integrated production line making phones. The probability of making a bad phone is 0.003. What is the probability that in a sample of 20 that you will have exactly 0 bad? (All answers to three decimal places.) What is the probability that you will have 1 or more bad? QUE STION 3 10 poir For the Poisson distribution which of the following is not true Events can happen at any of a large number of places with the unit of measurement (hour, square yard, and so on) At anv specific point the probability of an event is small

Explanation / Answer

Ans:

2)

Binomial distribution with n=20,p=0.003

P(0 bad phone)=20C0*0.0030*(1-0.003)20=0.942

P(1 or more bad phone)=1-P(0 bad phone)=1-0.942=0.058
