Answer

Final Answer: The probability of flipping 3 coins and getting all heads or all tails is $\frac{1}{4}$ .

Steps

Step 1 ：Consider all possible outcomes when flipping 3 coins. There are $2^{3} = 8$ possible outcomes (HHH, HHT, HTH, HTT, THH, THT, TTH, TTT).

Step 2 ：Identify the outcomes that are either all heads (HHH) or all tails (TTT). There are 2 such outcomes.

Step 3 ：Calculate the probability by dividing the number of desired outcomes by the total number of outcomes. The probability is $\frac{2}{8} = \frac{1}{4}$ .

Step 4 ：Final Answer: The probability of flipping 3 coins and getting all heads or all tails is $\frac{1}{4}$ .
