The heights of certain species of plants are normally distributed,

with the mean 24 cm and standard deviation 1 cm.
What is the probability that a plant chosen at random will be between 22 cm and 26 cm tall?
~~~~~~~~~~~~~~~~~~~

Using regular and widely known calculators TI-83 or TI-84 that are an arm to each student, 
we use the normal cumulative distribution function


    P = normalpdf(22, 26, 24, 1) = 0.9545.    ANSWER

Solved.

Otherwise, an awkward situation arises: I see that you do not understand what you write,
and, in addition, you do not care about it.
