Bayes theorem - solving an equation [Hinglish] | Probability | Grade 12 | Math | Khan Academy

In this video, we tackle a unique problem where we use a given probability to solve for an unknown variable in the initial setup. A bag contains a mix of two-headed coins and fair coins, with the number of each defined by a variable 'n'. Given that the total probability of picking a coin and tossing a head is 31/42, we set up an equation using the law of total probability and solve it to determine the value of 'n'.
