Final answer:
The probability of flipping three coins and getting two tails and one head using theoretical probability is 3/8.
Step-by-step explanation:
To find the probability of flipping three coins and getting two tails and one head using theoretical probability, we need to determine the total number of possible outcomes and the number of favorable outcomes.
The total number of outcomes when flipping three coins is 2^3 = 8 since each coin has 2 possible outcomes (heads or tails).
To get two tails and one head, we have 3 possible outcomes: TTH, THT, and HTT.
Therefore, the probability of flipping three coins and getting two tails and one head is 3/8.
