So welcome to our very first homework assignment.

これから皆さんに初めての課題を出します

This is number 1. [Homework Assignment #1]

まず第1問です

Just to recap, in the class we learned about localization. [Localization]

今までの講義では位置推定と

We learned about about histogram filters. [Histogram filters]

ヒストグラムフィルタについて学び

And we programmed some in Python. [Python]

Pythonでプログラミングもしました

So the homework assignment will cover this plus some very basic probability. [Probability]

この課題はそれに加え簡単な確率に関する内容が含まれます

[Question 1] In the first question, I'm going to ask you some very basic probability questions.

第1問では基本的な確率の問題を解いてもらいます

We have random variable X and the probability of 0.2.

任意の確率変数Xがあり確率は0．2です

What's the probability of the complement?

補集合の確率はいくつでしょう？

We have 2 random variables, X and Y, whose probability individually is 0.2.

2つの確率変数XとYがありそれぞれの確率は0．2です

And X and Y are independent. [X, Y independent]

XとYは独立の事象です

What's the probability of the joint X, Y?

XとYの同時確率はいくつでしょう？

And we have the variable P(X) with probability of 0.2,

次に確率変数Xがあり確率は0．2です

and we have 2 conditionals, P(Y|X) and P(Y|¬X), both 0.6.

2つの条件P（Y｜X）とP（Y｜¬X）がありそれぞれの確率は0．6です

What's the probability of Y?

Yの確率はいくつでしょう？

Here you have to apply total probability.

ここでは全確率の定理を使います
