The 3 flips are independent trials each with a probability of 1/2 for tails. Probability of 3 tails in a row is \[\frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}=you\ can\ calculate\]

Figure it out yourself the same we did the previous question. Write a table with all possible outcomes. Then see what fraction your desired outcome is of the total number of outcomes.
