Explanation:
Detailed explanation-1: -The sample space of a sequence of three fair coin flips is all 23 possible sequences of outcomes: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT.
Detailed explanation-2: -When 3 coins are tossed, the favourable outcome is HHH. So required probability = 1/8.
Detailed explanation-3: -A sample space is the set of all possible outcomes of a random experiment. When you toss a coin, there are only two possible outcomes-heads (h) or tails (t) so the sample space for the coin toss experiment is h, t .
Detailed explanation-4: -The number of different outcomes when three coins are tossed is 2 × 2 × 2 = 8. All eight possible outcome are HHH, HHT, HTH, HTT, THH, THT, TTH, and TTT.
