The probability of getting two tails when two fair coins are tossed is 14\frac{1}{4}41​.

Quick Scoop

When you toss two fair coins, the possible outcomes are:

  • HH (head, head)
  • HT (head, tail)
  • TH (tail, head)
  • TT (tail, tail)

Each of these 4 outcomes is equally likely. Only TT gives two tails, so:

Probability of two tails=number of favorable outcomestotal outcomes=14\text{Probability of two tails}=\frac{\text{number of favorable outcomes}}{\text{total outcomes}}=\frac{1}{4}Probability of two tails=total outcomesnumber of favorable outcomes​=41​

So the answer to “what is the probability of getting two tails when two coins are tossed?” is 14\frac{1}{4}41​. TL;DR: There are 4 equally likely outcomes, and only 1 of them is two tails, so the probability is 14\frac{1}{4}41​.
