A coin is tossed thrice and all eight outcomes are assumed equally likely. Let event E be “the first throw results in the head” and event F be “the last throw results in the tail”. What is the probability of E∩F ?
Answer & explanation
Correct answer: option 3
S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}
E: first throw results in head = {HHH,HHT,HTH,HTT}
F: Last throw result in tail = {HHT, HTT, THT, TTT}
