There are a fixed number of independent trials n. Each trial has only two (hence binomial) outcomes, either “success” or “failure”. For the trials, the probability of success, p is always the same, and the probability of failure, q = 1 − p, is also always the same. The expected value E ( X) = n p. tim richards linkedinWebApr 1, 2024 · 4.5: The normal distribution.

WebSo you see the symmetry. 1/32, 1/32. 5/32, 5/32; 10/32, 10/32. And that makes sense because the probability of getting five heads is the same as the probability of getting zero tails, and the probability of getting zero tails should be the same as the probability of getting zero heads. I'll leave you there for this video. WebWhen this is the case, we can use the normal curve to estimate the various probabilities associated with that binomial distribution.
