At a convention, there are 8 mathematics instructors, 13 computer science instructors, 4 statistics instructors, and 6 physics instructors. If an instructor is selected, fint the probability of getting a physics or a statistics instructor.

0.323

Step-by-step explanation:

Number of mathematics instructors=8

Number of Computer Science instructors=13

Number of Statistics instructors=4

Number of Physics instructors=6

Total Attendance = 8+13+4+6=31

Probability of Getting a Physics Instructor=6/31

Probability of Getting a Statistics Instructor=4/31

Pr (Getting a Physics OR Statistics Instructor)

=Probability of Getting a Physics Instructor+

Probability of Getting a Statistics Instructor

=6/31+4/31=10/31=0.323
