probability - Solving for N in a binomial distribution

WebThe probability of seeing exactly 1 Head is 2/4 because you count both ways it can happen and then multiply by the probability of each outcome. The outcome itself is (0.5) (0.5) = 0.25 since a head has prob = 0.5 and tail has prob = 0.5. Then multiply by the 2 outcomes that have one Head to get 2 (0.25) = 0.5.

"WebThus, in a probability distribution, binomial distribution denotes the success of a random variable X in an n trials binomial experiment. Following are the conditions to find binomial distribution: n is finite and defined. Each trial has only two possible outcomes: success and failure. The result of each trial is independent of other trials. " - Find n in binomial distribution

WebJan 29, 2024 · Step 1: Verify that the sample size is large enough to use the normal approximation. First, we must verify that the following criteria are met: np ≥ 5 n (1-p) ≥ 5 In this case, we have: np = 100*0.5 = 50 n (1-p) = 100* (1 – 0.5) = 100*0.5 = 50 Both numbers are greater than 5, so we’re safe to use the normal approximation.
