# 100: It has been estimated that only about 30% of California residents have adequate
earthquake supplies. Suppose you randomly survey 12 California residents. We are
interested in the number who have adequate earthquake supplies. (Bold #'s are
randomized.)

Expert Solution
Step 1
*Answer:
D)
P(X>=8) = P(X = 8) + P(X = 9) + ………….. + P(X=12)
= 12C8 0.38 (1-0.3)12-8 +………………………….. + 12C12 0.312 (1-0.3)12-12 = 0.07783
e)
For none ie X=0,
P(X=0) = 12C0 0.30 (1-0.3)12-0 = 0.01384
Similarly, For All ie X = 12
P(X=12) = 12C12 0.312 (1-0.3)12-12 = 0.000001
So, it is very less likely that none or all of the residents will have adequate earthquake.
