A small village, which has no hospital nearby, is served by three mobile units coming from three centers A, B, and C. These units also serve many other villages in the region. The units pass through the village several times a day and they appear on the average frequently. What is the probability that a waiting patient will be served by the unit coming from center B?
Now, suppose unit A can serve only adult males, unit B can serve adult females and children, but not adult males, and C can serve everyone. Furthermore, C makes half the number of trips to any village compared to A and B. What is the probability that a waiting adult male patient will be served by the first mobile unit arriving on the scene?
Answer) Probability that a waiting patient will be served by the unit coming from center B is 1/3 as here the favorable outcome is 1 that is B and the number of possible outcomes is 3 that is A,B, and C.
And the probability is given by the favorable outcome divided by the number of possible outcomes.
So the required probability is 1/3.
In second case probability would be 1/2, as here it is mentioned in the question that B cannot serve adult males,
So the number of possible outcomes is 2 that is A and C,
So, therefore, the probability that a waiting adult male patient will be served by the first mobile unit arriving on the scene is 1/2.
