Answer:
3/8 or 0.38
Step-by-step explanation:
- List all the possible combinations in sample space : {HHH, HHT, HTH, THH, THT, TTH, HTT, TTT}
- Count the number of combinations in Sample Space : S = 8
- Find the combinations that corresponds to the event : {THT, TTH, HTT}
- Count the number of elements that corresponds to the event : E = 3
- Use the formula : P(E) = n(E)/n(S)
- Substitute the values : P(E) = 3/8
- The answer is 3/8
- or if you want to answer in decimal, divide 8 by 3
- 3÷8 = 0.375
- round up the decimal to the nearest hundredth
- The other answer is 0.38
