Roll a fair die three (3) times.a) What is the probability of rolling at least one 6 dotted side () in 3 rolls of a fairdie? That is, calculate P(at least one in 3 rolls). For part a), use the complementrule..b) Now reconsider the same question - what is the probability of rolling at least one6-dotted side () in 3 rolls of a fair die? But, for part b), do NOT use thecomplement rule. Instead, add the probability that you roll exactly 1 six to theprobability that you roll exactly 2 sixes to the probability that you roll exactly 3 sixes.The manager of a fast-food restaurant has determined that 0.55 of all customers order a
