What is the probability of picking the winning combination (order does not matter)? (Round your answer to 6 decimal places.)

In the Minnesota Northstar Cash Drawing you pick five different numbers between 1 and 30.

We have to pick no\'s from 1 to 30

Total no. of cases could be = 30 C 5 = 142506

required cases are = 1

the probability of picking the winning combination (order does not matter) = 1/142506 = 0.0000070172
