To have no repeated digits, all four digits would have to be different, which is selecting without replacement. The probability of no repeated digits is the number of 4 digit PINs with no repeated digits divided by the total number of 4 digit PINs. This probability is.

The probability of throwing a 3 or a 4 is double that, or 2 in 6. This can be simplified by dividing both 2 and 6 by 2. Note that H represents heads and T represents tails:.

Example: At a car park there are vehicles, 60 of which are cars, 30 are vans and the remainder are lorries. If every vehicle is equally likely to leave, find the probability of: a a van leaving first. Solution: a Let S be the sample space and A be the event of a van leaving first. Probability of a van leaving first:.

Understanding the basic rules and formulas of probability will help you score high in the entrance exams. In mathematics too, probability indicates the same — the likelihood of the occurrence of an event. Either an event will occur for sure, or not occur at all.

Random Experiment : An experiment in which all possible outcomes are know and the exact output cannot be predicted in advance, is called a random experiment.
