Total number of people in ward = 16
Number of nurses = 10
Number of male nurses = 4
Number of female nurses = 6

Number of doctors = 6
Number of male doctors = 3
Number of female doctors = 3

We are to find the probability of selecting a female or a doctor.

Probability of selecting a female or a doctor = Probability of selecting a female + probability of selecting a doctor - probability of selecting a female doctor

Probability of selecting a female or a doctor = 9/16 + 6/16 - 3/16 = 3/4

Thus, the probability of selecting a female or a doctor is 3/4

Proportional Relationships

A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:

y=kx

for some constant k , called the constant of proportionality .

(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .")

This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

The graph of the proportional relationship equation is a straight line through the origin.
