In a lottery, a person chooses six different numbers at random from 1 to 20, and if these six numbers match with six numbers already fixed by the lottery committee, he wins the prize. What is the probability of winning the prize in the game?

given: six numbers are chosen from 1-20

formula:


we have to find the probability of winning the prize


total possible outcomes of selecting six numbers from 1-20 is 20C6


therefore n(S)= 20C6=38760


let E be the event that all six numbers match with the given number (as winning number is fixed)


n(E)=1


probability of occurrence of the event is
