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.

|dw:1364251372872:dw| There are 8 possible outcomes, and only 1 is three tails, so the probabilty of three tails is 1/8
