17 sty 2020 · Whenever we’re interested in finding the probability of n successes in a binomial experiment, we must use the following formula: P (exactly k successes) = nCk * pk * (1-p)n-k. where: n: the number of trials. k: the number of successes. C: the symbol for “combination”. p: probability of success on a given trial.
To calculate (x = value): binompdf(n, p, number) if "number" is left out, the result is the binomial probability table. To calculate P ( x ≤ value): binomcdf( n , p , number) if "number" is left out, the result is the cumulative binomial probability table.

15 kwi 2020 · The binomial distribution describes the probability of obtaining k successes in n binomial experiments. If a random variable X follows a binomial distribution, then the probability that X = k successes can be found by the following formula:
In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1 − p).
The probabilities for "two chickens" all work out to be 0.147, because we are multiplying two 0.7s and one 0.3 in each case. In other words. 0.147 = 0.7 × 0.7 × 0.3. Or, using exponents: = 0.7 2 × 0.3 1. The 0.7 is the probability of each choice we want, call it p. The 2 is the number of choices we want, call it k. And we have (so far): = p ...
