Use the normal approximation to the binomial distribution to answer this question. fifteen percent of all students at a large university are absent on mondays. if a random sample of 12 names is called on a monday, what is the probability that four students are absent?

0.1289

Step-by-step explanation:

Given : The proportion of all students at a large university are absent on Mondays. :

Sample size :

Mean :

Standard deviation =

Let x be a binomial variable.

Using the standard normal distribution table ,

             (1)

Z score fro normal distribution:-

For x=4

For x=3

Then , from (1)

Hence, the probability that four students are absent =

(x+3)(x+7)
