CUET Preparation Today
| 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 ? |
1/4 1/3 1/2 1/8 |
| 1/2 |
| 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} |
