Theoretical probability is the likelihood of an event happening based on all possible outcomes.
In this case, Jill has two dimes, so there are four possible outcomes: HH, HT, TH, TT.
Out of these four outcomes, three of them have at least one head: HH, HT, TH.
Therefore, the theoretical probability that at least one of the two coins will turn up heads is 75%.
So the answer is 75%.
