Jason bought 10 of the 30 raffle tickets for a drawing. what is the probability that jason will win all 3 of the prizes if once a raffle ticket wins a prize it is thrown away?

For the first drawing, there are  30  tickets altogether, and Jason
has  10  of them.  The probability that one of his tickets will win is

                                                               10 / 30 .

For the second drawing, there are  29  tickets altogether, and Jason
has  9  of them.  The probability that one of his tickets will win is

                                                                 9 / 29 .

For the third drawing, there are  28  tickets altogether, and Jason
has  8  of them.  The probability that one of his tickets will win is

                                                                 8 / 28 .

The probability that all three of these things will happen is

                      (10/30) x (9/29) x (8/28)  =  720 / 24,360

                                                             =  6 / 203  =  2.96 percent (rounded)
