The central processing unit requirements, for programs that will

execute, have a triangular distribution with a $=0\mathrm{.}05$ milliseconds, b $=$

$1\mathrm{.}1$ milliseconds, and c $=6\mathrm{.}5$ milliseconds. Find the probability

that the CPU requirement for a random program is $2\mathrm{.}5$ milliseconds or

less.
