Binomial Probability
4 Questions
QUESTION 1 of 4
Hello Professor,
I need help with this question, "What is the probability that when making random guesses on a fifty question multiple choice exam, with four answer choices for each question, that you miss only thirty-five of the questions?"
QUESTION 2 of 4
Hello Professor,
Can you explain the process for the homework in 4.4 number 23 please?
I only get 30 Choose 15, but I dont know my p or my q.
Please help.
Thank you
QUESTION 3 of 4
Hi professor,
I got number #24 wrong in section 4.4. these are my numbers but I think they are mixed up ?
n=50
x=4
p=.35
q=.65
QUESTION 4 of 4
I'm kind of confused on how to approach these problems (when n is larger than 25 and you cannot use the binomial table)
Use the normal approximation to calculate the probability that P( x >= 17) for n = 30, p = 0.50 .
