else v can also say like:
prob of gettin x20 in 1st pick is 1/50
for gettin 2 nos from 1st 19 19/49,18/48
for gettin 2 nos from last 30: 30/47,29/46
but a diff 1 may b picked 1st so no of ways is 5! but among 2 from 19 there will b rep so /2! and same for last 30 so another /2!
so v get
(1/50)*(19/49)*(18/48)*(30/47)*(29/46 )*5!/(2!*2!)
