数Aの確率の問題です 緑色の丸のところの2分の1はどこから来たのでしょうか 自分は2分の1ではなくここは1と考えたのですが、 なぜ2分の1になるのでしょうか？

1380 基本 例題 53 平面上の点の移動と反復試行 00000 右の図のように、東西に4本, 南北に5本の道路がある。 地点Aから出発した人が最短の道順を通って地点Bへ 向かう。 このとき、途中で地点を通る確率を求めよ。 ただし,各交差点で、東に行くか, 北に行くかは等確率 とし,一方しか行けないときは確率でその方向に行く ものとする。 A 基本52 指針 求める確率を A-PBの経路の総数 ABの経路の総数 CC から、 どの最短の道順も同様に確からしい場合の確率で、 本間は道順によって確率が異なる。 11.1 C₂ とするのは誤り!これは、 解答 例えば、Att→→P→Bの確率は ・1・1 22 2 1111 A→→P→Bの確率は したがって,Pを通る道順を、 通る点で分けて確率を計算する。 2222 右の図のように、 地点 C, D, C, D', P'をとる。 Pを通る道順には次の3つの場合があり,これらは互いに排反で ある。 [1] 道順A→C→C→P この 1/2×1/2×12×1×1-(12)=1/23 は [2] 道順A→D→D→P C D P (2 C D' Pr A この確率は C(1/2)(1/2)x1/2×1=3(1/2)=1/150 16 [3] 道順AP'→P この確率は よって、求める確率は 1 + 00 16 + 36 6 32 = 16 1 32 [1] fff →→ と進む。 [2] ○○○と進む。 〇には、1個と 12個が入る。 [3] ○○○○ ↑と進む。 〇には、2個と 12個が入る。

Scientists think that dinosaurs existed on Earth for almost 200 million years. 19 could these great beasts, some of which weighed thousands of pounds and stood 100 feet tall, suddenly disappear? 11 The most popular theory is that the dinosaurs were killed off when an asteroid into southern Mexico. The asteroid's collision caused earthquakes, fires, and tidal waves. Volcanoes erupted, spewing poisonous gases into the sky and lowering the oxygen level in the oceans. Plants died, removing the food source for plant-eating dinosaurs. As these dinosaurs died, there was no food for meat-eating dinosaurs. In a short period of time, the dinosaurs were gone, and the first mammals began to appear. Many scientists note that, 21 the asteroid had a major impact, the Earth's climate had already scientists claim that mammals already on Earth before the asteroid might have 22 the extinction begun to change. The planet was cooling, and the colder temperatures were likely killing plants. Some by eating dinosaur eggs. We may never know for certain what caused the extinction of the dinosaurs. But it was most likely the result of a combination of the asteroid, colder climates, and egg-stealing mammals 23 the single event of the asteroid hitting the Earth. 2024年度 全学 Casey Malarcher et al., Reading for the Real World 1, Second edition When ② 19 What 3 Who 4 How came ② carried 20 3 crashed 4 burst 21 while once 3 unless 4 yet 22 ① governed obstructed 3 facilitated 4 united 23 1 other than rather than ③ except for 4 owing to
