The questions here will be provided, as per NCERT guidelines. Bottom line is that, as long as you can simulate the outcome generating process with a computer (with programming or otherwise), you can empirically estimate the probability of any outcome. Compute the probability of randomly guessing the answers and getting exactly 9 questions correct. 1/3. People have also asked me for recommendations on probability theory and statistics books that give a decent overview of all important concepts from these fields. Of course, doing it like that is just extremely laborious (especially for more complicated processes), so it’s much better to use a computer simulation. Probability Example 1. And I really mean that. Tagged in. P(at least one head) = 1 – P(all tails) = 1 – 1/32 = 31/32. How likely something is to happen. D. none. Therefore, it is a very important chapter.
