$b_1=\frac{1}{2} \\ q=\frac{1}{2} \\S=\frac{b_1}{1-q} \\ S=\frac{\frac{1}{2}}{1-\frac{1}{2}}=\frac{\frac{1}{2}}{\frac{1}{2}}=1$ Ответ: 1

When and why Andrew have to leave Blaenely?
What did Andrew do as to find a new job?
What did Andrew come to Aberalaw?
How many candidates took part in the competition for vacant position in the Aberalaw Medical Society?

So Andrew had to leave Blaenely in a month. He began immediately to look for another position. He read all the advertisements in the newspapers and sent many applications to doctors who wanted an assistant, but by the end of the second week, he had received no answer to his applications. Andrew really began to worry. Three weeks passed and he almost lost hope to find a job. In the evening of the 30th of August he met Denny in the street. “I’m rather sorry you are going, Manson,” he said. “I want to tell you something. I heard this afternoon that the Aberalaw Medical Society is looking for a new assistant. It is thirty miles from here. Why don’t you try?” “Well, yes,” Andrew agreed slowly. “I may try.” A few minutes later he walked home to write one more application.On the sixth of September Andrew came to Aberalaw. The Aberalaw Medical Society was to select a new doctor out of seven candidates that had sent in their applications for this position. The selected doctor would have to work at a coal mine. All seven candidates had been asked to come. Andrew was the third to enter the room of the Committee. About thirty miners filled the room. At a small table in the middle of the room he saw Owen, the secretary, and Llewelyn, the head doctor. Owen, in a quiet voice, explained the conditions of work there. Then the miners asked Andrew many questions about his work and himself, and then he left the room and the next candidate went in and then the next. It was over at last. All the candidates were waiting. The door opened and Owen invited Manson again.
