📌What's in the video: In this video, we will solve in detail question 1 from the 471st question of the 2026 Summer Matriculation Exam, Term A, which deals with the topic of normal distribution. We will learn how to correctly use a normal distribution table to calculate areas and percentages and find the standard deviation from the question data. We will present a clear and winning method for finding exact quantities of items and complementary percentages using a conversion table and cross-multiplication. We will deal with complex sections that require calculating the amount of plants that were not included in certain categories in combination with percentages. Finally, we will see how to calculate the new average of the population when the standard deviation changes in the following year in a simple way. 📌 Link to the question in the video: https://kibinimatika.org/wp-content/u... 📌For all the solutions to this matriculation exam on the Kibinimatika website: https://kibinimatika.org/bagroot471h2026 💬 Join our community on Discord - for questions, answers and guidance: 🔗   / discord   🌐 Our website:https://kibinimatika.org 🔗 For all our study groups and community: https://kibinimatika.org/groop 📚Our groups on Telegram:https://t.me/ovadgroups 🔥Oved Lev's update channel Ari: https://whatsapp.com/channel/0029VbAD... 🧮Link to playlist:    • 🎓 פתרון בגרות 471 חורף 2026 שאלה 6-חקירת פ...   Like, comment and subscribe to the channel help the content reach more students!
