There are 13 people in the unit, so 13 will always be the number of possible outcomes.

The probability of selecting a nurse is 8/13, since 8 of the 13 people are nurses.

The probability of selecting a male is 3/13 because 10 people (7 nurses and 3 physicians) are women.

If you are asking the probability of selecting either a nurse OR a male, you would add the two probabilities and subtract the chance of a male nurse, which is 1/13.

That leaves a summary probability of 10/13.

If this or another answer here proves helpful in your research, you can encourage good answers by choosing one answer as the “best answer.”

There are 13 people altogether.

8 nurses plus 2 male physicians.

8/13 + 2/13 = 10/13

Please say if you do not understand and I will explain further!

ITS JUST TOO HARD!!
