Probability</h3>
Question Parameters:
- The probability is 0.6 that a patient selected at random from the current residents of a certain hospital will be a male.
- The probability that the <u>patient </u>will be a male who is in for surgery is 0.2.
Generally the equation for the probability the patients is in the hospital surgery is mathematically given as
X= a patient selected at random is male/the <u>patient </u>will be a male who is in for surgery
Therefore

X=1/3
