When doing a coin flip, there are 2 outcomes, H and T. 2 flips can be 4 outcomes, HH, TT, HT, and TH, 4 outcomes. 3 flips would be HHH, TTT, HHT, TTH, HTT, THH, HTH, and THT, 8 outcomes. A 1 in 8 chance (1/8) is for a 3 in a row heads.
Answer:
12.5% or 1/8
Step-by-step explanation:
Each time you flip the coin, you have a 1/2 chance of getting a heads.
If you do this three times, then your chances are 1/2 x 1/2 x 1/2, which is 1/8, or 12.5%.
