Casey buys a Venus chocolate bar every day during a promotion that promises'one in six wrappers is a winner'. Assume that the conditions of the binomialdistribution apply: the outcomes for Casey's purchases are independent, and thepopulation of Venus chocolate bars is effectively infinite. Find the probability thatCasey gets no winning wrappers in seven days. Casey buys a bar every day forsix weeks. Find the probability that he gets at least three winning wrappers. *None of the choicesO -0.277* 0.270* 0.979

Determine whether the given procedure results in a binomial distribution. If it is not binomial, identify the requirements that are not satisfied. Randomly selecting 100 citizens of a state and recording their nationalities Choose the correct answer below. O A. No, because the probability of success does not remain the same in all trials. B. No, because there are more than two possible outcomes. O C. Yes, because all 4 requirements are satisfied. O D. No, because there are more than two possible outcomes and the trials are not independent. Click to select your answer.

Determine whether or not the procedure described below results in a binomial distribution. If it is not binomial, identify at least one requirement that is not satisfied. Seven hundred different voters in a region with two major political parties, A and B, are randomly selected from the population of 7000 registered voters. Each is asked if he or she is a member of political party A, recording Yes or No. Choose the correct answer below. O A. No, the probability of success is not the same in all trials. O B. No, the trials are not independent and the sample is more than 5% of the population. OC. No, there are more than two possible outcomes. O D. No, the number of trials is not fixed. O E. Yes, the result is a binomial probability distribution.
