Estimate it as a relative frequency from real data, calculate it from equally likely outcomes, and watch a simulated coin converge on 0.5 as the law of large numbers takes hold.</description></item><item><title>Lesson 2 - Probability Rules</title><link>https://datatweets.com/courses/statistics/probability-fundamentals/lesson-2-probability-rules/</link><pubDate>Fri, 14 Nov 2025 09:00:00 +0200</pubDate><guid>https://datatweets.com/courses/statistics/probability-fundamentals/lesson-2-probability-rules/</guid><description>Meet sample spaces, events, and the probability axioms, then master the two rules you reach for first — the complement rule for &amp;rsquo;not&amp;rsquo; and the addition rule for &amp;lsquo;or&amp;rsquo; (mutually exclusive and general).</description></item><item><title>Lesson 3 - Solving Complex Probability Problems</title><link>https://datatweets.com/courses/statistics/probability-fundamentals/lesson-3-solving-complex-probability-problems/</link><pubDate>Fri, 14 Nov 2025 09:00:00 +0200</pubDate><guid>https://datatweets.com/courses/statistics/probability-fundamentals/lesson-3-solving-complex-probability-problems/</guid><description>Combine events with the multiplication rule, tell independent from dependent events using real penguin data, preview conditional probability, and solve &amp;lsquo;at least one&amp;rsquo; problems with the complement.</description></item><item><title>Lesson 4 - Permutations and Combinations</title><link>https://datatweets.com/courses/statistics/probability-fundamentals/lesson-4-permutations-and-combinations/</link><pubDate>Fri, 14 Nov 2025 09:00:00 +0200</pubDate><guid>https://datatweets.com/courses/statistics/probability-fundamentals/lesson-4-permutations-and-combinations/</guid><description>Learn to count the ways things can happen: the counting principle, factorials, permutations (order matters) and combinations (order doesn&amp;rsquo;t), and how to turn those counts into probabilities.</description></item><item><title>Lesson 5 - Guided Project: The Odds of the Lottery</title><link>https://datatweets.com/courses/statistics/probability-fundamentals/lesson-5-guided-project-lottery-odds/</link><pubDate>Fri, 14 Nov 2025 09:00:00 +0200</pubDate><guid>https://datatweets.com/courses/statistics/probability-fundamentals/lesson-5-guided-project-lottery-odds/</guid><description>The module capstone: use counting, combinations, and the probability rules to compute the true odds of a 6/49 lottery — the jackpot, every partial win, how many tickets buy a real chance, and why no &amp;rsquo;lucky&amp;rsquo; combination beats the math.</description></item></channel></rss>
