Detailed explanation-1: -Outcome-Flipping Two Coins. In an experiment of flipping two coins, there are four possible outcomes.-All of the outcomes of this experiment are shown below pictorially.
Detailed explanation-2: -Tossing a coin or rolling a die are examples of random experiments. Whenever we talk about probability there is a random experiment behind it. We talk about probability in the context of such an experiment.
Detailed explanation-3: -Experimental probability describes how frequently an event actually occurred in an experiment. So if you tossed a coin 20 times and got heads 8 times, the experimental probability of getting heads would be 8/20, which is the same as 2/5, or 0.4, or 40%.
Detailed explanation-4: -When two coins are tossed, the sample space is HH, HT, TH, TT
Detailed explanation-5: -When a fair coin is tossed then there are two possible outcomes: H(head), T(tail). This probability of occurrence of both events will be 0.5.
