1. An average of 4 out of 8 customers in a restaurant, are asking for green tea with their meal.
A random sample of 8 customers is selected. Show your work and use binomial to find the probability that:
(i) Exactly 2 ask for green tea with their meal?
(ii) Less than 7 ask for green tea with their meal?
Homework Answers
X ~ B ( n = 8 , P = 0.5 )
Part i)
Part ii)
P ( X < 7 ) = 1 - P ( X >= 7 )
P ( X < 7 ) = 1 - 0.0351
P ( X < 7 ) = 0.9649
