Question 1172809: In a large population, about 45% of people prefer tea over coffee. A researcher takes a random sample of 13 people and surveys whether they prefer tea over coffee.
Use the binomial distribution to compute the probability that exactly 6 of the people in the sample prefer tea over coffee.
Identify the following information required to find the probability of people who prefer tea over coffee.
n= _ trials
x= _ successes
p= _ probability of those who prefer tea

Instead of doing this routine calculations for you,  I will refer to the lessons

    - Simple and simplest probability problems on Binomial distribution
    - Typical binomial distribution probability problems
    - How to calculate Binomial probabilities with Technology (using MS Excel)
    - Solving problems on Binomial distribution with Technology (using MS Excel)
    - Solving problems on Binomial distribution with Technology (using online solver)

in this site.

You will find there many similar typical problems of this class,  solved and explained with all details.

So,  learning from these lessons,  you will be able to solve such problems on your own, which is your
PRIMARY  MAJOR  GOAL  visiting this forum  (I believe).

            - it is  YOU  who needs practice.

            - We,  the tutors,  do not need it.
