Please help with the following exercise

(a) Write down the mathematical presentation of a logistic regression model consisting of five predictor variables X1,X2,X3,X4, and X5. (b) Given a trained logistic regression model consisting of two predictor variables X1 and X2 shown below, Ca11: glm(formula =YX1+X2, family = binomial, data = trai: i. Choose the significant predictor(s) and write down a reasonable logistic regression model. Justify your answer. ii. If X1=1,525,X2=8,330, what would be the predicted class label by using the logistic regression model defined by Question 4.b(i) ? (c) Briefly describe the procedure of creating a ROC curve based on a trained logistic regression classifier
