2. Example
The lifetime risk of developing lung cancer is about 1.25%.
(a) What is the probability of that you ask ten people before one
says he or she has lung cancer?
(b) Find the (i) mean and (ii) standard deviation.
Solution:
(a) P = 0.0125
q = 1- 0.01 = 0.9875
x=10
= = モ1
= 10 = (0.0125)(0.9875)101
= 10 = 0.0112
