What is the at least once rule Explain how the at least once rule can be used to find the correct probabilities in the games of the Chevalier de Mere What is the at least once rule OA P at least one event A in n trials 1 P A n trials B P at least one event A in n trials 1 P A 1 trials OC P at least one event A in n trials 1 P A in n trials OD P at least one event A in n trials 1 P no A in n trials Explain how the at least once rule can be used to find the correct probabilities in the games of the Chevalier de Mere OA Each roll is a dependent event and the probability of an event occurring or not each roll is simpler to calculate than the probability that it will occur a specific number of times OB Each roll is an independent event and the probability of an event occurring or not each roll is simpler to calculate than the probability that it will occur a specific number of times OC Each roll is a dependent event and the at least once rule calculates the probability of a single event D Each roll is an independent event and the at least once rule calculates the probability of a single event
