Math Probability for English Learners - 数学確率基礎口頭試験問題回答例

flip a coin

数学というのは、計算をして解を得ることと考えがちですが、その考え方や概念は学校ではもちろん、ビジネスでは日常使われていることです。これを英語で話せることは、英語学習者には不可欠です。

数学を英語で話す機会はほとんどないと思いますので、書いておきます。

Q: Explain the basic concept of probability according to the lecture.

A. A basic concept of probability is explained in this video. A “fair” coin means that it has an “equal chance” of landing on one side or another when you flip it; landing on either side is “equally likely” to occur. One side is called “heads” and another “tails.” The probability is obtained by dividing the number of possibilities that meet the conditions by the number of equally likely possibilities. If you run an experiment of this fundamentally random event of getting heads by flipping a coin many times, the result would eventually converge to 50%. If you roll a “fair” die, there are six equally likely possibilities and the probability of rolling one side is one out of six; while the probability of rolling one or three is one out of three; however, the probability of rolling two “and” three is zero because rolling two “and” rolling three are “mutually exclusive” events.
