    ➡️Since either coin can turn up Head (H) or Tail (T), are the possible outcomes.

    ➡️Here coin is tossed twice, then sample space is S = (TT, HH, TH, HT)

    ➡️∴ Number of possible outcomes n (S) = 4

    ➡️Let A be the event of getting at least one tail

    ➡️∴ n (A) = 3

    ➡️P(Event) = Number of outcomes favorable to event/ Total number of possible outcomes

    ➡️P(A) = n(A)/n(S)

    ➡️= ¾

    No. of possible outcomes 4

    This outcomes are :- HH, TH, HT, TT

    Hence, possibility of tail is 3/4 ans.
