When using a rule of multiplication, there are two to choose from.
You use the rule P(A and B) = P(A) x P(B) when the events A and B are independent.
Probabilities are used in mathematics and statistics and are found in everyday life, from weather forecasts to sporting events.
With a little practice and a few tips, the process of calculating probabilities can be more manageable. One important tip when solving a probability word problem is to find the keyword, which helps to identify which rule of probability to use.

From Ramanujan to calculus co-creator Gottfried Leibniz, many of the world's best and brightest mathematical minds have belonged to autodidacts.
And, thanks to the Internet, it's easier than ever to follow in their footsteps (or just finish your homework or study for that next big test).
Most probability questions are word problems, which require you to set up the problem and break down the information given to solve.
The process to solve the problem is rarely straightforward and takes practice to perfect.
