Hi, I have this problem here that I am trying to solve:
A box contains three coins with a head on each side, four coins with a tail on each side, and two fair coins. If one of these nine coins is selected at random and tossed once, what is the probability that a head will be obtained?
Here is what I think:
1) A: the event that one of the three coins with a head on each side is chosen.
B: the event that one of the four coins with a tail on each side is chosen.
C: the event that one of two fair coins is chosen.
P(A)=1/8, P(B)=1/16, P(C)=1/4
P(a head will be obtained)= ? I don't know where to start from there now.
