Anon: Do you know how to calculate probabilities like P10, P20, P30...? I do not understand lot of this statistics stuff and desperately need help. Thanks

Help with Calculating Probabilities 
MathMate,
You can review your teacher's class notes, and the textbook, which should be selfexplanatory.
You are probably stuck with notations, which are usually described at the beginning of the notes or textbook.
Probabilites are numbers between 0 and 1, and represent the likelihood of a certain event happening.
If Q represents the event of drawing a queen from a 52card deck, then
P(Q)=4/52 since there are four queens in a 52 card deck, and we assume that the probability drawing any of the cards from a 52card deck is equal.
Other than that, you can post a specific question that represents a typical problem with which you need help.
