.إنني أزعم أنها نحو 8%

私は約８％の確率だと考えます。

.في الواقع، وكما سنرى، ستكون النتيجة عند 8 1/3%، بطريقة حسابية

実際、数学的な答えは８と1/3％になります。

،والسبيل لمشاهدة ذلك هو هذا المخطط

それをこの図を使って理解しましょう。

.الذي يمثل منطقة النتائج الإيجابية في الاختبار

ここは陽性と診断された人のエリアです。

،وبالحصول على نتيجة إيجابية في الاختبار، تعرفون أنكم في هذه المنطقة

陽性と診断されたので、あなたはこのエリアにいます。

.ولن يهم أي شيء آخر

他のことは置いておきましょう。

.أنتم تعرفون أنكم في هذه الدائرة

あなたはこの円の中にいます。

ولكن في هذه الدائرة، تظل نسبة المنطقة السرطانية

しかしこの円の中の人で、実際に癌である可能性は

.إلى المنطقة بأكملها صغيرة جدًا

円全体に比べると、かなり小さいですね。

.ولكنها تتزايد

検診結果の陽性を受けて

،ويتضح أنه بالحصول على نتيجة إيجابية في الاختبار، تتغير احتمالية السرطان

あなたが癌である可能性は確かに高まりました。

.ويزيد العامل بمقدار ثمانية تقريبًا

しかし、それはたかだか８％程度なのです。

.كما سنرى بعد قليل

すぐに納得できるしょう。
