Solution:
The question appears to be related to probability and asks for the description of the sample space and outcomes for a trial in which 2 coins are tossed, and each coin can show either a head (H) or a tail (T).The sample space for this experiment (tossing two coins) consists of all the possible outcomes that can occur. Since each coin has 2 possible outcomes, and there are 2 coins, there are 2 x 2 = 4 possible outcomes in total for the sample space $$ S $$.The sample space can be written as:\[ S = \{ (H, H), (H, T), (T, H), (T, T) \} \]Here, each pair represents the outcome of the two coins, with the first element in the pair representing the outcome of the first coin, and the second element representing the outcome of the second coin.
