Suppose we collect data for a group of students in CS 598 with variables X_{1}X1 = average hours studied per week, X_{2}X2 = undergrad GPA, and YY = receive an A. We fit a logistic regression with the estimated coefficients given by b0=6, b1=0.5 and b2=1.

The probability that a student who studies for 3 hours per week (on average) and has an undergrad GPA of 3.5 gets an A is __________[a]. (Round your answer to 2 digits after the decimal point.)

In order to have a more than 50% chance of getting an A in Stat542, the student needs to study at least __________[b] hours per week (on average).

solve for [a] and [b]
