次の英文を読んで、(1)~00までの文がその内容とあっていれば〇をそうでなければ×を解答 用紙に記入しなさい。 Florence Nightingale Florence Nightingale was born on May 12, 1920, into a wealthy family in England, and received the most luxurious education from an early age, learning not only foreign languages like French, Greek, and Italian, farmers she visited for charity work, she gradually began to think that she wanted to work in a job that but also mathematics, astronomy, psychology, and literature. However, after seeing the lives of poor served people. When she turned 30, she decided to become a nurse and started working at a hospital in London. Nightingale, who eventually became a director of a women's hospital, began to advocate the need for nurses with specialized training. At that time, nurses had a low status and were considered nothing more than servants who cared for the sick. A major turning point occurred in 1854. War began in Crimea*, present-day Ukraine, and Nightingale was sent there with 24 Catholic sisters and 14 nurses. Nightingale's efforts improved the hospital environment during the war. The Nightingale School of Nursing was established with the Nightingale Fund created during the war. Although Henri Dunant, a founding member of the International Committee of the Red Cross, highly praised her work, Nightingale was not involved in the International Committee of the Red Cross. This was because she believed that aid activities based on self-sacrifice by participants would not last long. Her famous quote, "Devotion without sacrifice is true service," expresses this well. It is said that this was due to the idea that "we rely on the spirit of service of our members, but without financial support, we are powerless." Nightingale only served wounded soldiers as a nurse for only two years during the Crimean War*, and became famous for her symbolic image of dedication and for her use of statistics to reform health care. The statistical methods she used at this time were highly praised, and she was considered a pioneer of statistics in England. Nightingale suffered from poor health from a young age, and is said to have spent most of her time in bed after returning from Crimea. Nightingale passed away peacefully at the age of 90 at her home in London on August 13, 1910. advocate* 主張する Crimea* クリミア半島 Crimean War* クリミア戦争 (1) Florence Nightingale was born in a wealthy family and she learned many foreign languages.

次の問題で1枚目の左上の(2)と演習問題の(2)は同じ様な問題だと思うのですが2枚目は演習問題の答えなのですが何故左上の問題は経路を一つ一つ分けて計算しているのでしょうか?

204 第7章 確 率 礎問 126 道の確率 i) P→C→B→Rとすすむ場合, 進路が2つある交差点は, PとCの2点 よって,i)である確率は(12-1 205 右図のような道があり, PからQまで最短経路で すすむことを考える. このとき, 次の問いに答えよ. (1) 最短経路である1つの道を選ぶことが同様に確 からしいとして, Rを通る確率を求めよ. R P (2) 各交差点で, 上へ行くか右へ行くかが同様に確からしいとき 2XRを通る確率を求めよ. 精講 (1)題意は「仮にPからQまで道が5本あったとしたら, 1つの道 を選ぶ確率は1/3」ということです. (2) 題意は「ある交差点にきたとき,上または右を選ぶ確率がそれぞれ1/23」と いうことです. iii) P→C→D→Rとすすむ場合, 進路が2つある交差点は, P,C,D の3点 よって,)である確率は (12/1 = i), ii), )は排反だから、求める確率は 1 1 1 7 + 2 4 8 8 注 上の(1),(2)を比べると答が違います. もちろん, どちらとも正解 です.確率を考えるとき 「同様に確からしいのは何か?」 ということ が,結果に影響を与えます. また,(1)と(2)でもう1つ大きな違いがあります. それは, (1) では 「Qにつくまで」 考えなければならないのに対して, (2) では 「Rにつ いたら,それ以後を考える必要がない」 点です. 解 答 (1) PからQまで行く最短経路は 4! 3!1! -=4 (通り) (4C でもよい) また,PからRまで行く最短経路は 3! -=3(通り) (3C1 でもよい) 2!1! 112 RからQまで行く最短経路は1通りだから PからRを通りQまで行く最短経路は 3×1=3 (通り) よって, 求める確率は 3 4 (2)(1) より題意をみたす経路は3本しかないことがわかる. ここで, A, B, C, D を右図のように定める. i) P→A→B→R とすすむ場合, 進路が2つある交差点はPのみ. 1 よって, i) である確率は 2 B R PCD ポイント 道の問題では,次のどちらが同様に確からしいかの判 断をまちがわないこと I. 1つの最短経路の選び方 Ⅱ. 交差点で1つの方向の選び方 演習問題 126 右図のような道があり, PからQまで最短 経路ですすむことを考える. このとき,次の 問いに答えよ.
