can you please help.. and if possible can u provide me as well with excel formulas to use

A reseller of a garage wishes to set up in a shopping arcade. He estimates that he will be able to sell 110 cars a day and the sales are two to two independent. A study showed him that, among the different brands available, brand A accounts for 38.6% of the market. We denote by X the random variable which, on a given day, associates the number of brand A devices sold on that day.. Applying the appropriate approximation, answer the following questions: A) Calculate the probability that, on a random day, there are exactly 25 brand A devices sold. B) Calculate the probability of the event: "on a given day, at least 30 of the cars sold are of brand A\" 0) Determine a value for the probability of the event: "on a given day, the number of brand A cars sold is between 25 and 45"
