1. S = {(R , R ), (R , G), (R , B ), (G, R ), (G, G), (G, B ), (B , R ), (B , G), (B , B )}
The probability of each point in S is 1/9.
2. S = {(R , G), (R , B ), (G, R ), (G, B ), (B , R ), (B , G)}
3. S = {(e , e , . . . , e ), n ≥ 2} where e ∈(heads, tails}. In addition, e = e =
1 2 n i n n −1
heads and for i = 1, . . . , n − 2 if ei = heads, then ei +1 = tails.
P {4 tosses} = P {(t , t , h , h)} + P {(h , t , h , h)}

6. If E (F ∪ G) occurs, then E occurs and either F or G occur; therefore, either E F
or EG occurs and so
E (F ∪ G) ⊂ E F ∪ EG

2 Introduction to Probability Models
Similarly, if E F ∪ EG occurs, then either E F or EG occurs. Thus, E occurs and
either F or G occurs; and so E (F ∪ G) occurs. Hence,
E F ∪ EG ⊂ E (F ∪ G)
which together with the reverse inequality proves the result.
7. If (E ∪ F )c occurs, then E ∪ F does not occur, and so E does not occur (and so E c
does); F does not occur (and so F c does) and thus E c and F c both occur. Hence,
(E ∪ F )c ⊂ E c F c
If E c F c occurs, then E c occurs (and so E does not), and F c occurs (and so F does
not). Hence,
