You are the teacher of two math classes of 20 and 25 students respec a university program, the students need a 75% in the class. Suppose ea probability of getting atleast a 75% in the class. Let X1 be the numbe class of 20 who receive atleast a 75%. Let X2 be the number of studen who receive atleast a 75%. a. Do X1 and X, fit the binomial setting? Are there any issues? For the rest of the question, assume both X1 and X2 can be modeled b
