Question

Using the Binomial distribution, If n=10 and p-03, find P(x=3) A manufacturing machine has a 6% defect rate. If 4 items are chosen at random, what is the probability that at least one will have a defect? About 3% of the population has a particular genetic mutation. 700 people are randomly selected. Find the mean for the number of people with the genetic mutation in such groups of 700 About 9% of the population has a particular genetic mutation 800 people are randomly selected. Find the standard deviation for the number of people with the genetic mutation in such groups of 800

Explanation / Answer

Ans 1

p=0.7 q = 1-0. =0.3

P(X=4) = C(8,4)*(0.3^4)*(0.7^4)

70*(0.3^4)*(0.7^4) = 0.136
