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).

The sat and act tests use very different grading scales. the sat math scores follow a normal distribution with mean 518 and standard deviation of 118. the act math scores follow a normal distribution with mean 20.7 and standard deviation of 5. suppose regan scores a 754 on the math portion of the sat. how much would her sister veronica need to score on the math portion of the act to meet or beat regan's score?
