The mathematics department of a college has 1515 male professors, 77 female professors, 1414 male teaching assistants, and 1414 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.

probability that the selected person is a professor or a male.=

Step-by-step explanation:

The mathematics department of a college has 15 male professors, 7 female professors, 14 male teaching assistants, and 14 female teaching assistants

number of professors = 15 male + 7 female = 22

number of male = 15 male professor + 14 male assistants= 29 male

number of professors are male = 15

selected person is professor or a male = professors + male - number of male professors= 22+29-15= 36

Total persons = 15+ 7 +14+14= 50

probability that the selected person is a professor or a male.=
