\begin{minipage}{9cm}
The 1984 “California Avocado
Society” study of more than two
hundred twenty-five million
avocados determined that the
weight of avocados is normally
distributed with a mean of 215~grams and a standard
deviation of 5~grams.

Only avocados weighing between
210~grams and 225~grams are
considered fit for sale.

\begin{enumerate}[a)]
    \item \nbPointsEnumi{3}\textbf{Show} that 81.5\% of avocados are fit for sale.

    \item \nbPointsEnumi{2}\textbf{Determine} the probability that an avocado weighs more than
215~grams, given that it is fit for sale.

Give the answer as a fraction of integers.
