SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Use a probability tree to show the possible outcomes for flipping a coin 3 times
STEP 2: Write the required number of outcomes
[tex]\begin{gathered} number\text{ of total outcomes}=8 \\ All\text{ heads}=(HHH) \\ n(All\text{ heads\rparen}=1 \end{gathered}[/tex]STEP 3: Calculate the probability of getting all heads
[tex]\begin{gathered} Probability(All\text{ heads\rparen}=\frac{number\text{ of All head}}{number\text{ of total outcomes}} \\ Pr(All\text{ heads\rparen}=\frac{1}{8} \end{gathered}[/tex]Hence, the probability of getting all heads when flipping a coin 3 times is 1/8
