Вероятность достать шар красного или зеленого цвета, равна

СРОЧНО!! ПОМОГИТЕ!! ПОЖАЛУЙСТА!! УМОЛЯЮЮЮ!!! Переведите пожалуйста, и ответье на вопросы!! Rob's story Part 2 What's the matter with you? The next day I opened my eyes and saw the soldier. He was in bed and his face was very pale. He had a very bad cough too. "What's the matter with you?" I asked, "Have you got a cold?" "I don't know," said the soldier, "but I have a headache and a sore thoat." I wanted to call the doctor and tried to open the door but I couldn't. I looked out of the window and couldn't belive my eyes. All the people from our house were in the street. They closed the door to the house. "Please help us! The soldier is ill," I cried. "If you go out, you'll kill us. It's the plague," they answered and ran away. At they moment I understood everything. I wasn't in Russia, and it wasn't a game. But how did I get to the Edinburgh of hundreds of years ago? Was I mag? Was it a bad dream? I didn't know the answer. I looked at the soldier. He was real. I touched his forehead. His temperature was high - that was real too. " If I don't help him, he'll die. And I'll die too," I thought and opened my rucksack. There were a lot of medicines in my rucksack. I had an aspirin, some nose drops and some cough syrup. I gave my medicine to the soldier. " If you don't have the plague, my medicine will help you. You must stay in bed and drink a lot of water, " I said to him. Two days later the soldier was better. It wasn't the plague. It was flu. But when I told him about it, he didn,t believe me. "You have some secret medicine and you can cure any disease," he said. " I must go back to London tomorrow. If you come with me, I'll do anything for you." The soldier and I went to London. His name was Phillip and he wasn't a bad man. The road to London was long and difficult, but finally we got there. Вопросы переведите и ответье на ни, пожалуйста!! Умоляю)) 1) How did the soldier look in the morning? 2) Why were the people scared? 3) What did Rob understand? 4) What happened to the soldier? 5) How did Rob help him? 6) Did the soldier die?
