Asked by urmilaagarwal | 10 Mar, 2019, 10:28: AM
Expert Answer
Possible events = { HH, HT , TH, TT }
( HT means, head in a coin tail in another coin. similar meaning for other events )
Each event is equally probable, hence probability of each event is 1/4.
probability of getting one head and one tail = p(HT) + p(TH) = (1/4)+(1/4) = 1/2
