You are performing 7 independent Bernoulli trials with p = 0.2 and q = 0.8. Calculate the probability of the stated outcome. Check your answer using technology. (Round your answer to five decimal places.)
P(X≥3) = _______
n = 7 , p = 0.2
P(X) = ncx px ( 1 - p)n-x
So,
P( X >= 3) = 1 - P( X <= 2)
= 1 - [ P (x = 0) + P( X = 1) + P (X = 2) ]
= 1 - [ 7C0 0.20 0.87 + 7C1 0.21 0.86 + 7C2 0.22 0.86 ]
= 0.14803

Suppose X1,X2,…,Xn represent the outcomes of n independent Bernoulli trials, each with success probability p. Note that we can write the Bernoulli distribution as: Suppose X1 2 X, represent the outcomes of n independent Bernou i als, each with success probabil ,p. Note that we can writ e the Bernoulǐ distribution as 0,1 otherwise Given the Bernoulli distributional family and the iid sample of X,'s, the likelihood function is: -1 a.

You perform a sequence of m+n independent Bernoulli trials with success probability p between (0, 1). Let X denote the number of successes in the first m trials and Y be the number of successes in the last n trials. Find f(x|z) = P(X = x|X + Y = z). Show that this function of x, which will not depend on p, is a pmf in x with integer values in [max(0, z - n), min(z,m)]. Hint: the intersection of...

Negative Binomial experiment is based on sequences of Bernoulli trials with probability of success p. Let x+m be the number of trials to achieve m successes, and then x has a negative binomial distribution. In summary, negative binomial distribution has the following properties Each trial can result in just two possible outcomes. One is called a success and the other is called a failure. The trials are independent The probability of success, denoted by p, is the...
