You roll a ten-sided number polyhedron that has the numbers 1 through 10 on its faces. Each face has a different number. You observe the number that ends up on top. Let A be the event “the number is less than 6” and B be the event “the number is odd”.
A. Find P(A), P(B), and P(A and B).
B. Find P(A)+P(B)−P(A and B).
C. Find P(A or B).
