Binomial and poisson distribution examples
WebFor those situations in which n is large and p is very small, the Poisson distribution can be used to approximate the binomial distribution. Recall the binomial probability distribution: P (X = x) = {n \choose x}p^x (1-p)^ {n-x}, \qquad x = 0, 1, 2, . . . , n. As in the “100 year flood” example above, n is a large number (100) and p is a ...

Binomial Distribution Examples And Solutions. Example 1: If a coin is tossed 5 times, find the probability of: (a) Exactly 2 heads (b) At least 4 heads. WebFinal answer. Step 1/3. The Binomial distribution is used to model the number of successes in a fixed number of trials, where each trial has two possible outcomes - success or failure. The Normal distribution and Poisson distribution are commonly used to approximate the Binomial distribution under certain circumstances.
