Solution: p(not rolling a 4) = 1 − p(rolling a 4 ) = 1 − 1 6 = 5 6 2. (2 pt) What is the probability of getting at least one 4 in five rolls of a single die? Solution: p(not rolling a 4 in five rolls ) = 1 − [p(not rolling a 4 in one roll )]5 = 1 − [ 5 ]5 ≈ .598 6 3. (1 pt) What is the probability of rolling either a 1 or 2 on a singe die? Solution: p(rolling a 1 or 2) = p(rolling a 1)+p(rolling a 2) = 1 6 + 1 6 = 1 3 4. (1 pt) Suppose you toss three coins. What is the probability of getting three tails? Solution: p(tossing 3 T)=p(tossing a T)*p(tossing a T)*p(tossing a T) = 1 1 2 ∗ 1 2 ∗ 1 2 = 1 8 ...
