The mathematics department of a college has 13 male professors, 10 female professors, 11 male teaching assistants, and 13 female teaching assistants. If a person is selected at random from the group, find the probability that the selected person is a professor or a male.

Step-by-step explanation:

GIVEN: The mathematics department of a college has male professors, female professors, male teaching assistants, and female teaching assistants.

TO FIND: If a person is selected at random from the group, find the probability that the selected person is a professor or a male.

SOLUTION:

Total employees in mathematics department

Total males in mathematics department

Probability that selected person is a male

Total professor (male+female)

Probability that selected person is professor

Total male professor

Probability that selected person is a male professor

Probability that selected person is a professor or a male

Hence probability that selected person is a professor or a male is

the slope of the line is 60

one point on the line is (40,10)

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
