Final answer:
The probability of obtaining two heads when flipping two fair coins is 1/4.
Step-by-step explanation:
To find the probability of obtaining two heads when flipping two fair coins, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
When flipping two coins, there are a total of 2 x 2 = 4 possible outcomes (HH, HT, TH, TT).
Out of these outcomes, only 1 outcome results in two heads (HH).
Therefore, the probability of obtaining two heads is 1/4, which is the simplest form of the answer.
