青チャート数学1aの例題46についてです。[2]のAかつBを求めるときに2つのサイコロを区別して考えるとどちらも6が出る事象は1通りではなく2通りでカウントするべきだと思います。ですが、答えは1通りでカウントしています。なぜですか?

5 A Matter of Taste Reading Passage 042 At the age of just 22, Jamie Oliver became well known across the UK as "The Naked Chef." He called himself this not because he cooked wearing no clothes, but because he wanted to simplify food preparation so that everybody could follow his recipes. He wanted to "strip down" the idea of cooking. Since then he has had numerous TV shows, published 50 many books, and has become a household name in the UK. Today, one of the activities Jamie Oliver is best known for is his great effort to improve the school dinners that children eat every day. One day, he visited the kitchen of a typical London secondary school, and he was shocked to see how much processed junk food the kids were given to eat each day. Fat and sugar levels were extremely high, and nutritional values very 10 low. The "turkey twizzler" became the symbol of these unhealthy meals: processed meat containing 21.2% fat and only 34% actual turkey. Oliver ran the school kitchen for one year and tried to show that it was possible to serve healthy meals on a limited budget—and that kids actually enjoyed eating them. His mission was to radically change the eating habits of children in that school, and across the country. 150 200 15 20 25 CULTIES 250 His project (the "Feed Me Better" campaign) has had some influence on school dinners in the UK. After watching the documentary Jamie's School Dinners, 271,677 people signed a petition calling for healthier school meals. This led the Prime Minister to agree to spend 280 million pounds (about 37 billion yen) on school dinners, to ban some junk food from school menus, and to create a School Food Trust to provide support and advice for people preparing school meals. Research, by the way, shows that children who stop eating sugary, fatty food and instead eat Oliver's school dinners are better behaved in class, and they get higher test 300 scores, too. 350 Of course, the project has had some problems. At first, many students (and even parents) resisted the removal of the junk food they were so used to. In one famous instance, some parents were passing local takeaway food to their children through the school fence. Also, schools that followed the plan for a while were often found to gradually drift back into bad habits. After all, it is easier and cheaper to just give the kids junk food. However, Oliver's efforts represent a positive start, and with obesity becoming such a huge problem (see Unit 4), 400 it's a very necessary start.

この問題なのですが、解答を見ると『彼が〜』という答えになっています。 なぜ、『彼が』が主語に出来るのか分かりません。 解答頂けると嬉しいです

強 56 ・Let's try How far it is possible for him to be a good husband is doubtful. もありません。この場合, How ~で、名詞のかたまりを作っているので この文は, How から始まっていますが,これは感嘆文でも、疑問文で す。 far は距離や程度を表し, How far ~ で, 「どのくらい~か」とい う意味になります。 それでは, How ~の節の範囲はどこまででしょうか How far it is possible 「それがどの程度可能であるか」 そのあとで, for him to be a good husband is ….. for ~to一の形は例題6で説明しましたね。 to-はもちろん, is を含む はずもなく, husband までです。 it = for ~to-の形で, How~の節も husband までとなります。 すると,この文は, [How ~] is doubtful. となっていることがわかりますね。 []部分が名詞として文の主語となっ ているのです。 Ulla 「彼がよい夫であることがどの程度可能なのかは疑わしい」 かなりあやしいものだといっているわけです。> また, that については, that が接続詞なのか関係詞(例題33~39) のか,それとも代名詞なのか判断できるようにしましょう ① He said that ten years ago. 代名詞「彼はそれを10年前に言った」 ② He said that word to me. bluora od 代名詞,形容詞的用法 「彼はその言葉を私に言った」 ③ He says that he was rich ten years ago. 接続詞 「彼は10年前は金持ちだったと言っている」
