PROBABILITY

Probability is the likelihood that something will occur. Probability can be expressed as a fraction, decimal, or precentage. Probability is generally expressed as a fraction, then the fraction is changed to a decimal, and then the decimal can be changed to a percentage. Probability =    the number of favorable outcomes                              the number of possible outcomes Example:   In my drawer I have 9 pair of socks.  Two (2) pair are red, three (3) pair are blue, and five (5) pair are black.         a.  What is the probability that I will pull out a red pair?        Probability(of pulling out a red pair) = the number of red in drawer                                                                the number of socks in drawer                                             P (red)    =       2                                                                          9        b.  What is the probability that I will pull out a black pair?        Probability(of pulling out a red pair) = the number of black in drawer                                                                the number of socks in drawer                                             P (red)    =       5                                                                              9
