Question

Consider a binomial experiment with n = 9 trials where the probability of success on a single trial is p = 0.10.

(Round your answers to three decimal places.)

(a) Find P(r = 0).

(b) Find P(r ≥ 1) by using the complement rule.

Answer #1

**Solution:**

Given:

n = 9

p = 0.10

**Part a)** Find P(r = 0).

Binomial probability formula :

Where q = 1 – p = 1 - 0.10 = 0.90

thus

**Part b)** Find P(r ≥ 1) by using the complement
rule.

Consider a binomial experiment with 16 trials and probability
0.65 of success on a single trial.
(a) Use the binomial distribution to find the probability of
exactly 10 successes. (Round your answer to three decimal
places.)
(b) Use the normal distribution to approximate the probability
of exactly 10 successes. (Round your answer to three decimal
places.)

A binomial experiment consisting of n trials resulted in
observations y1, y2,..., yn, where
yi = 1 if the ith trial was a success and yi = 0
otherwise. Find the MLE (MaximumLikelihood Estimator) of p, the
