Two fair coins are tossed. Define
A = Getting a head on the first coin
B = Getting a head on the second coin
A and B = Getting a head on both the first and second coins
A or B = Getting a head on the first coin, or the second coin, or both coins
a. Find P(A) = the probability of A.
b. Find P(B) = the probability of B.
c. Using the multiplication rule (Rule 3b), find P(A and B).
d. Using the addition rule (Rule 2a), find P(A or B).
