What is the probability of getting a) both tails b) a head and a tail c) at least one head; d) not getting at least one tail, when two unbiased coins are tossed? Solution Experiment : Tossing two unbiased coins Total Number of Possible Choices ...
The ways in which the coins can land are: HHHTTHTT There are four possible results with just one of the ways giving HH. Thus the probability of obtaining HH is ¼ = 0.25. There were two possible outcomes from the experiment of tossing the first coin and two possible outcomes from the...
