Each of the digits​ 0-9 is written on a slip of​ paper, and the slips are placed in a hat. If 5 slips of paper are selected at​ random, determine the probability that the 5 numbers selected are greater than 3.

The  number  of possible sets  that could  be drawn  from choosing any  5  of  the  10 numbers =    10 C 5    =  252

 

And  the  number  of possible  sets  drawn from ( 4,5,6,7,8,9)  = 6C5  =  6

 

So

 

P( that all  5  numbers  drawn are > 3)  =   6 / 252   =   1 /  42
