430 (2) 白玉7個と黒玉3個が入った袋から, 5個の玉を同時に取り出すとき、 出る白玉の個数をXとする。 このとき, 確率変数 X の確率分布を求めよ。 p.428 428 基本事項」 また,確率P(3≦X≦4) を求めよ。 確率分布 基本例題 50 (1) 5枚の硬貨を同時に投げるとき, 裏の出る枚数をXとする。このとき、 確率変数Xの確率分布を求めよ。 また, 確率P (X≧2) を求めよ。 CHART & SOLUTION 確率分布 (確率の総和)=1の確認 TORS まず 確率変数Xのとりうる値を調べ, その値をとるときの確率P を求める。 求めた確率の総和が1になっているかどうかを確認し, なっていない場合はとりうる値に ヌケがないかチェックする。 (1) P(X ≧ 2)..... Xが2以上の値をとる確率。 また P(X≧2)=P(X=2)+P(X=3)+P(X=4)+P(X=5) 解答 (1) 確率変数Xのとりうる値は 0, 1, 2 3 4 5 である。 それぞれの値をとる確率は P(x=0)=(1/2)=132 5 P(X=1)=6C₁ (2) = 32 P(X=2)=C(+)(²) = 32 P(X=3)=P(X=2)=- P(X=4)=P(X=1)=- 1 P(X=5)=P(X=0)= 32 10 よって, Xの確率分布は次の表のようになる。 P X 0 1 2 34 5 計 1 5 10 10 5 1 32 32 32 32 32 32 P(X≧2) = || 10 32 5 32 26 13 32 16 10 10 5 1 + + + 32 32 32 32 || 1 (Z)NSE #69 - P(X=r) = 0 C + ( + ) ( ² ) F 約分しない。 右の INFORMATION 参照。 裏の出る枚数が3枚の とき,表の出る枚数は2 枚。また, 表の出る枚数 が2枚である確率は, 裏 の出る枚数が2枚であ る確率と等しい。 (確率の総和)=1

[4] Read the instructions and write a well-organized answer in English. (50 points) Virtual reality (VR)* refers to a high-quality simulation of reality created by a computer. Probably the most famous use for VR so far is gaming. But VR has also been used to improve society in various fields such as education, medicine, and engineering. Describe a single specific way that virtual reality can be used to improve society. Explain your idea in detail in about 100 English words. Notes: Virtual reality (VR)*: VR systems use special glasses that completely cover the user's eyes. These glasses show a very realistic picture of a world created by the computer. In addition, the systems can tell when the user moves their head, arms, and sometimes other body parts. So users can control the action by natural movement. Some systems even let users feel like they are touching things. Thus, VR systems can make users feel like they are really in another world. 〔答案〕 I suggest you to simulation with VR. For example, doctors can practice operation. I have the three reasons. First, VR's display is very real. So doctors can do as if real simulation. Second, every one can make simulation software. If you want add patients information to VR and study how to make software, you can make VR software to yourself. Third, medical professors can use VR simulation in lecture. If they do this, Students who want be surgeon in the future will reduce about operation's anxiety. In this way, VR have a lot of possibilities that useful of medical field. For these reasons, I suggest VR simulations.

humans. "We were able to identify one of the many molecular features that likely shape behavior," she adds. ** hol boquete es Though the origins of the dog/human partnership remain unknown, it's becoming increasingly clear that each species has changed (during our long years header The physical differences between a basset hound and wolf are obvious, but dogs have also changed in ways that are more than skin (or fur) deep. One recent study shows how by bonding with us and learning to work ogether with humans, dogs may have actually become worse at working together Their pack lifestyle and mentality appear to be reduced and are far as a species. less prevalent even in wild dogs than in wolves. But, Yale's Laurie Santos says, dogs may have compensated in other interesting ways. They've learned to use humans to solve problems. "Several researchers have presented dogs and wolves with an impossible problem (e.g., a puzzle box that can't be opened or a pulling tool that stops working) and have asked how these different species react," Santos explains. Researchers have found that wolves try lots of different trial and error tactics to solve the problem - they get at it physically. But at the first sign of trouble, dogs do something different. They look back to their human companion for help. This work hints that dogs may have lost some of their physical problem-solving abilities in favor of more social strategies, ones that rely on the unique sort of cooperation
