Answer:
The expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.
Step-by-step explanation:
The data provided is:
Opinion
Front Footage For Undecided Against Total
Under 45 feet 12 4 4 20
45-120 feet 35 5 30 70
Over 120 feet 3 2 5 10
Total 50 11 39 100
The formula to compute the expected frequency is:

Compute the expected frequency for people against the project and who have over 120 feet of property foot frontage as follows:


Thus, the expected frequency for people against the project and who have over 120 feet of property foot frontage is 3.9.

To find P(A and C) we have to simply multiply the probabilities of getting an A with that of getting a C
P(A)=0.6
P(C|A)=0.3
P(A and C)=0.6*0.3
=0.18
