A small business employs 35 people. A statistical study can admit that on a given day, the probability that an employee is absent is 0.05. We assume that employee absences occurring on a given day are independent of each other. We denote by X the random variable which, on each day drawn at random, represents the number of absent employees. 1) Explain why X follows a binomial distribution. Give the parameters of this law. 2) Calculate the probability of the following events: a) E1: "On a given day, there are exactly three absentees ". b) E2: "On a given day, there are strictly more than two absentees "; c) E3: "On a given day, the number of absentees is between 3 and 5 (limits included)". 3) Calculate the expectation noted E (X) of the random variable X
