Probability is a mathematical
concept that shows up in a number of real world situations.
Probability is the chance that something will happen. The person
playing this game of Trouble needs the die to land on a "4" to win the
game. The probability of that happening on the next move is found
by using the formula:
number of outcomes that can
occur to give you what you are trying to do .
number of possible outcomes
Check out this website about probability
for more of an introduction. The site covers some of the basic
definitions associated with probability and gives plenty of examples of
how to find the chance that different events will happen. (By the
way, the probability of the player winning Trouble on his next move is
1/6 or 1 out of 6 chance).
