Let X be a binomial distribution with n = 50 and p = .23 what is the probability that x = 10, that is P(X=10)=
Group of answer choices
a) 0.023
b) 2.3
c) 0.12
d) 0.20
Solution
Given that ,
Using binomial probability formula ,
P(X = x) = (n C x) * px * (1 - p)n - x
P(X = 10) = (50 C 10) * 0.2310 * (0.77)40
= 0.12
Probability = 0.12
option c) is correct
Part II. Applying the Binomial distribution. 1. If x is binomial with n-50, pro.9, use Excel to compute P(x s 40)- 2. A student takes a multiple choice test with 100 questions. Each question has 4 choices and only one choice is correct. The student guesses the correct answer for each question. If xenumber of correct guesses, then x is a binomial random variable. Fill in the following values: a) n b) To pass the test, the student must get...

compute p(x) using the binomial probability formula. then determine whether the normal distribution can be used to estimate this probability. if so, p(x) using the normal distribution and compare the result with the exact probability. n=78, p= 0.83, and x=60 for n= 78, p= 0.83, and x=60, find P(x) using the binomial probability distribution. P(x) _. (round to four decimal places as needed.) can the normal distribution be used to approximate this probability? A. no, the normal distribution cannot be...
