Complete parts (a) through (d) below. (a) What is the probability that all seven have danced in public while under the influence of alcohol? (Round to four decimal places as needed.) (b) What is the probability that at least one has not danced in public while under the influence of alcohol? (Round to four decimal places as needed.) (c) What is the probability that none of the seven have danced in public while under the influence of alcohol? (Round to four decimal places as needed.) (d) What is the probability that at least one has danced in public while under the influence of alcohol? (Round to four decimal places as needed.)
