Three coins are tossed once. Let A denote the event ‘three heads show”, B denote the event “two heads and one tail show”
When three coins are tossed, the sample space is given by S = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT} Accordingly, A = {HHH} B = {HHT, HTH, THH} C = {TTT} D = {HHH,...

Three unbiased coins are tossed together. Find the probability of getting (i) two heads.
Here S = {HHH, HHT, HTH, THH, TTH, THT, HTT, TTT} (i) Favourable number of elementary events = 3 [HHT, HTH, THH] ∴ P (two heads) = 3/8 (ii)...
