If you mean 'at least' 2 heads, the probability is 50%. If you mean exactly 2,
the probability is 3/8, or 37.5%.
There are 3 independent coin tosses, each of which is equally likely to come up
heads or tails. That's a total of 2 * 2 * 2 or 8 possible outcomes (HHH, HHT, HTH,
etc.). Of these, 4 include 2 or 3 heads, which is half of 8. Only 3 include exactly 2
heads, so the probability of that is 3/8.
