A small fishing boat leaves from the south bank of the Allegheny River and heads at an
80° angle with an engine speed of 20 knots. However, the eastward force of the current
carries the boat along so it actually travels at a 60° angle with the shore.
How fast is the current, and how fast does the boat actually travel?
1. Enter a random seed using the
RandSeed
command.
2. Assuming the urn contains 10 red balls
and 25 white balls, simulate picking 5
balls at random from the urn without
replacement. Enter
drawball({10,25},5)
.
Result: 2 red balls and 3 white balls.
