Question

3. 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 patient will be a male who is in for surgery is .2. A patient randomly selected from current residents is found to be a male; what is the probability that the patient is in the hospital for surgery?

Answer 1

We have that the the probability that the patient is in the hospital for surgery is mathematically given as

X=1/3

Probability

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 patient 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 patient will be a male who is in for surgery

Therefore

$X=\frac{0.2}{0.6}$

X=1/3
